1. We have isolated and sequenced a mouse replacement variant histone H3.3 cDNA. It corresponds to the most abundant mRNA expressed from a unique gene by the use of one out of three polyadenylation sites. The 3' non coding region of H3.3 is very long (approximately 1100 nt) and highly conserved throughout evolution since it is about 95% homologous to the 3' non coding region of the chicken H3.3B gene. We studied the expression of the H3.3 gene during SV40- and polyoma-induced mitotic host reaction in confluent, Go-arrested primary mouse kidney cell cultures. H3.3 replacement variant mRNA steady state levels increased during the Go to S-phase transition, apparently as the result of two mechanisms: one related to cell growth, whereas the other was linked to cellular DNA synthesis. The latter mechanism was however far less pronounced than with replication histone variant mRNAs. The biological implications of these results are discussed. PMID: [2470025] 

2. The histone family of proteins is subdivided into two major groups: the main type histones, which are synthesized in coordination with DNA replication during the S-phase of the cell cycle, and the replacement histones, which can be synthesized in the absence of DNA replication substituting main type histone isoforms. Accumulation of replacement histone variants has been observed in several terminally differentiated tissues that have stopped cell division. The replacement subtype of the H3 class is termed H3.3. This protein is encoded by two different genes (H3.3A and H3.3B) that both code for the same amino acid sequence, but differ in nucleotide sequences and gene organization. This has been shown for human and avian H3.3A and H3.3B genes and for a murine H3.3B cDNA. In an attempt to define patterns of replacement histone H3.3 gene expression during male germ cell differentiation, we have constructed mouse testicular cDNA libraries and have isolated cDNAs corresponding to the murine H3.3A and H3.3B genes. Using probes specific for these two different genes we show by RNase protection analysis and by nonradioactive in situ hybridization with testis sections that H3.3A mRNA is present in pre- and postmeiotic cells, whereas expression of the H3.3B gene is essentially restricted to cells of the meiotic prophase. PMID: [9373943] 

3. Replacement-variant H3.3 histones have been isolated and sequenced in different eukaryotes, but no functional H3.3A gene has been characterized in the mouse so far. We have cloned an H3.3A cDNA from a mouse fetal ovary library, differentially screened with testis versus somatic cDNA probes. We showed this gene contains a region homologous to the reverse and complementary alpha-globin gene. We believe such a structure could have been generated by retroposition during the evolution of both globin and histone gene families. The sequence coding for H3.3A is 76.6% homologous to the mouse H3.3B gene at the nucleotide level and differs in only one amino acid at the protein level. The high degree of homology between these genes and the H3.3 variant histones from other eukaryotes reveals the conservation of these replication-independent class of histones throughout evolution. Analysis of gene expression reveals a developmental regulation concurrent with meiotic progression, with the highest level of transcript detection coincident with meiotic onset during both oogenesis and spermatogenesis.

4. This study describes comprehensive polling of transcription start and termination sites and analysis of previously unidentified full-length complementary DNAs derived from the mouse genome. We identify the 5' and 3' boundaries of 181,047 transcripts with extensive variation in transcripts arising from alternative promoter usage, splicing, and polyadenylation. There are 16,247 new mouse protein-coding transcripts, including 5154 encoding previously unidentified proteins. Genomic mapping of the transcriptome reveals transcriptional forests, with overlapping transcription on both strands, separated by deserts in which few transcripts are observed. The data provide a comprehensive platform for the comparative analysis of mammalian transcriptional regulation in differentiation and development. PMID: [16141072] 

5. The National Institutes of Health's Mammalian Gene Collection (MGC) project was designed to generate and sequence a publicly accessible cDNA resource containing a complete open reading frame (ORF) for every human and mouse gene. The project initially used a random strategy to select clones from a large number of cDNA libraries from diverse tissues. Candidate clones were chosen based on 5'-EST sequences, and then fully sequenced to high accuracy and analyzed by algorithms developed for this project. Currently, more than 11,000 human and 10,000 mouse genes are represented in MGC by at least one clone with a full ORF. The random selection approach is now reaching a saturation point, and a transition to protocols targeted at the missing transcripts is now required to complete the mouse and human collections. Comparison of the sequence of the MGC clones to reference genome sequences reveals that most cDNA clones are of very high sequence quality, although it is likely that some cDNAs may carry missense variants as a consequence of experimental artifact, such as PCR, cloning, or reverse transcriptase errors. Recently, a rat cDNA component was added to the project, and ongoing frog (Xenopus) and zebrafish (Danio) cDNA projects were expanded to take advantage of the high-throughput MGC pipeline.

6. The H3L histone variant gene in Paracentrotus lividus (sea urchin) shows almost all typical features of the replication-dependent histone genes, but it codes for the H3.3 histone protein with the S.//. A.IG amino acid motif, which is typical of the variants synthesized in a replication-independent manner. "H3L-like" histone genes have been found in several unrelated organisms. These genes are intronless and encode for the typical H3.3 histone proteins. The newly described family of H3L-like variants, nearly ubiquitous within the animal kingdom, could represent the common ancestor of H3 and H3.3 histone genes. PMID: [15638457] 

7. Histone H3 (H3) phosphorylation at Ser(10) occurs during mitosis in eukaryotes and was recently shown to play an important role in chromosome condensation in Tetrahymena. When producing monoclonal antibodies that recognize glial fibrillary acidic protein phosphorylation at Thr(7), we obtained some monoclonal antibodies that cross-reacted with early mitotic chromosomes. They reacted with 15-kDa phosphoprotein specifically in mitotic cell lysate. With microsequencing, this phosphoprotein was proved to be H3. Mutational analysis revealed that they recognized H3 Ser(28) phosphorylation. Then we produced a monoclonal antibody, HTA28, using a phosphopeptide corresponding to phosphorylated H3 Ser(28). This antibody specifically recognized the phosphorylation of H3 Ser(28) but not that of glial fibrillary acidic protein Thr(7). Immunocytochemical studies with HTA28 revealed that Ser(28) phosphorylation occurred in chromosomes predominantly during early mitosis and coincided with the initiation of mitotic chromosome condensation. Biochemical analyses using (32)P-labeled mitotic cells also confirmed that H3 is phosphorylated at Ser(28) during early mitosis. In addition, we found that H3 is phosphorylated at Ser(28) as well as Ser(10) when premature chromosome condensation was induced in tsBN2 cells. These observations suggest that H3 phosphorylation at Ser(28), together with Ser(10), is a conserved event and is likely to be involved in mitotic chromosome condensation. PMID: [10464286] 

8. N-terminal tail phosphorylation of histone H3 plays an important role in gene expression, chromatin remodeling, and chromosome condensation. Phosphorylation of histone H3 at serine 10 was shown to be mediated by RSK2, mitogen- and stress-activated protein kinase-1 (MSK1), and mitogen-activated protein kinases depending on the specific stimulation or stress. Our previous study showed that mitogen-activated protein kinases MAP kinases are involved in ultraviolet B-induced phosphorylation of histone H3 at serine 28 (Zhong, S., Zhong, Z., Jansen, J., Goto, H., Inagaki, M., and Dong, Z., J. Biol. Chem. 276, 12932-12937). However, downstream effectors of MAP kinases remain to be identified. Here, we report that H89, a selective inhibitor of the nucleosomal response, totally inhibits ultraviolet B-induced phosphorylation of histone H3 at serine 28. H89 blocks MSK1 activity but does not inhibit ultraviolet B-induced activation of MAP kinases p70/85(S6K), p90(RSK), Akt, and protein kinase A. Furthermore, MSK1 markedly phosphorylated serine 28 of histone H3 and chromatin in vitro. Transfection experiments showed that an N-terminal mutant MSK1 or a C-terminal mutant MSK1 markedly blocked MSK1 activity. Compared with wild-type MSK1, cells transfected with N-terminal or C-terminal mutant MSK1 strongly blocked ultraviolet B-induced phosphorylation of histone H3 at serine 28 in vivo. These data illustrate that MSK1 mediates ultraviolet B-induced phosphorylation of histone H3 at serine 28. PMID: [11441012] 



Dynamic changes in the modification pattern of histones, such as acetylation, phosphorylation, methylation, and ubiquitination, are thought to provide a code for the correct regulation of gene expression mostly by affecting chromatin structure and interactions of non-histone regulatory factors with chromatin. Recent studies have suggested the existence of an interplay between histone modifications during transcription. The CBP/p300 acetylase and the CARM1 methyltransferase can positively regulate the expression of estrogen-responsive genes, but the existence of a crosstalk between lysine acetylation and arginine methylation on chromatin has not yet been established in vivo. PMID: [12498683] 

10. The nuclear hormone receptor co-activator CARM1 has the potential to methylate histone H3 at arginine residues in vitro. The methyltransferase activity of CARM1 is necessary for its co-activator functions in transient transfection assays. However, the role of this methyltransferase in vivo is unclear, given that methylation of arginines is not easily detectable on histones. We have raised an antibody that specifically recognizes methylated arginine 17 (R17) of histone H3, the major site of methylation by CARM1. Using this antibody we show that methylated R17 exists in vivo. Chromatin immunoprecipitation analysis shows that R17 methylation on histone H3 is dramatically upregulated when the estrogen receptor-regulated pS2 gene is activated. Coincident with the appearance of methylated R17, CARM1 is found associated with the histones on the pS2 gene. Together these results demonstrate that CARM1 is recruited to an active promoter and that CARM1-mediated R17 methylation on histone H3 takes place in vivo during this active state. PMID: [11751582] 



Histone H3 (H3) phosphorylation plays important roles in mitotic chromosome condensation. We reported that H3 phosphorylation occurs at Ser28, as well as at Ser10 during mitosis, at least in mammals. Aurora B was recently demonstrated to be responsible for Ser10 phosphorylation in S. cerevisiae, C. elegans, Drosophila and Xenopus egg extract. PMID: [11856369] 

12. Covalent modifications to histone proteins are well documented in the literature. Specific modification sites are correlated with chromatin structure and transcriptional activity. The histone code is very complex, and includes several types of covalent modifications such as acetylation, methylation, phosphorylation, and ubiquitination of at least 20 possible sites within the histone proteins. The final chromatin structure "read-out" is a result of the cooperation between these many sites of covalent modifications. Methylation and acetylation sites of histone H3 from many different species have been previously identified. However, a full post-translational modification status on histone H3 from mouse has not yet been reported. Here we demonstrate the use of high-accuracy matrix-assisted laser desorption/ionization time-of-flight and nanoelectrospray ionization tandem mass spectrometry to identify the methylation and acetylation sites of the mouse histone H3. In addition to the sites previously identified from other species, one unique methylation site, Lys-122, from mouse histone H3 was identified. The reported mass spectrometric method provides an efficient and sensitive way for analyzing post-translational modifications of histone proteins. PMID: [13678296] 

13. Methylation of arginine residues within histone H3 has been linked to active transcription. This modification appears on the estrogen-regulated pS2 promoter when the CARM1 methyltransferase is recruited during transcriptional activation. Here we describe a process, deimination, that converts histone arginine to citrulline and antagonizes arginine methylation. We show that peptidyl arginine deiminase 4 (PADI4) specifically deiminates, arginine residues R2, R8, R17, and R26 in the H3 tail. Deimination by PADI4 prevents arginine methylation by CARM1. Dimethylation of arginines prevents deimination by PADI4 although monomethylation still allows deimination to take place. In vivo targeting experiments on an endogenous promoter demonstrate that PADI4 can repress hormone receptor-mediated gene induction. Consistent with a repressive role for PADI4, this enzyme is recruited to the pS2 promoter following hormone induction when the gene is transcriptionally downregulated. The recruitment of PADI4 coincides with deimination of the histone H3 N-terminal tail. These results define deimination as a novel mechanism for antagonizing the transcriptional induction mediated by arginine methylation. PMID: [15339660] 

14. Protein arginine methyltransferases (PRMTs) have been implicated in transcriptional activation and repression, but their role in controlling cell growth and proliferation remains obscure. We have recently shown that PRMT5 can interact with flag-tagged BRG1- and hBRM-based hSWI/SNF chromatin remodelers and that both complexes can specifically methylate histones H3 and H4. Here we report that PRMT5 can be found in association with endogenous hSWI/SNF complexes, which can methylate H3 and H4 N-terminal tails, and show that H3 arginine 8 and H4 arginine 3 are preferred sites of methylation by recombinant and hSWI/SNF-associated PRMT5. To elucidate the role played by PRMT5 in gene regulation, we have established a PRMT5 antisense cell line and determined by microarray analysis that more genes are derepressed when PRMT5 levels are reduced. Among the affected genes, we show that suppressor of tumorigenicity 7 (ST7) and nonmetastatic 23 (NM23) are direct targets of PRMT5-containing BRG1 and hBRM complexes. Furthermore, we demonstrate that expression of ST7 and NM23 is reduced in a cell line that overexpresses PRMT5 and that this decrease in expression correlates with H3R8 methylation, H3K9 deacetylation, and increased transformation of NIH 3T3 cells. These findings suggest that the BRG1- and hBRM-associated PRMT5 regulates cell growth and proliferation by controlling expression of genes involved in tumor suppression. PMID: [15485929] 

15. Nuclear factor kappaB (NF-kappaB) plays an important role in the transcriptional regulation of genes involved in inflammation and cell survival. Here, we show that coactivator-associated arginine methyltransferase CARM1/PRMT4 is a novel transcriptional coactivator of NF-kappaB and functions as a promoter-specific regulator of NF-kappaB recruitment to chromatin. Carm1 knockout cells showed impaired expression of a subset of NF-kappaB-dependent genes upon TNFalpha or LPS stimulation. CARM1 forms a complex with p300 and NF-kappaB in vivo and interacts directly with the NF-kappaB subunit p65 in vitro. CARM1 seems to act in a gene-specific manner mainly by enhancing NF-kappaB recruitment to cognate sites. Moreover, CARM1 synergistically coactivates NF-kappaB-mediated transactivation, in concert with the transcriptional coactivators p300/CREB-binding protein and the p160 family of steroid receptor coactivators. For at least a subset of CARM1-dependent NF-kappaB target genes, the enzymatic activities of both CARM1 and p300 are necessary for the observed synergy between CARM1 and p300. Our results suggest that the cooperative action between protein arginine methyltransferases and protein lysine acetyltransferases regulates NF-kappaB-dependent gene activation in vivo.

16. Post-translational modifications of conserved N-terminal tail residues in histones regulate many aspects of chromosome activity. Thr 3 of histone H3 is highly conserved, but the significance of its phosphorylation is unclear, and the identity of the corresponding kinase unknown. Immunostaining with phospho-specific antibodies in mammalian cells reveals mitotic phosphorylation of H3 Thr 3 in prophase and its dephosphorylation during anaphase. Furthermore we find that haspin, a member of a distinctive group of protein kinases present in diverse eukaryotes, phosphorylates H3 at Thr 3 in vitro. Importantly, depletion of haspin by RNA interference reveals that this kinase is required for H3 Thr 3 phosphorylation in mitotic cells. In addition to its chromosomal association, haspin is found at the centrosomes and spindle during mitosis. Haspin RNA interference causes misalignment of metaphase chromosomes, and overexpression delays progression through early mitosis. This work reveals a new kinase involved in composing the histone code and adds haspin to the select group of kinases that integrate regulation of chromosome and spindle function during mitosis and meiosis. PMID: [15681610] 

17. The mitogen-activated protein kinase cascades elicit modification of chromatin proteins such as histone H3 by phosphorylation concomitant with gene activation. Here, we demonstrate for the first time that the mixed lineage kinase-like mitogen-activated protein triple kinase (MLTK)-alpha phosphorylates histone H3 at Ser28. MLTK-alpha but neither a kinase-negative mutant of MLTK-alpha nor MLTK-beta interacted with and phosphorylated histone H3 in vivo and in vitro. When overexpressed in 293T or JB6 Cl41 cells, MLTK-alpha phosphorylated histone H3 at Ser28 but not at Ser10. The interaction between MLTK-alpha and histone H3 was enhanced by stimulation with ultraviolet B light (UVB) or epidermal growth factor (EGF), which resulted in the accumulation of MLTK-alpha in the nucleus. UVB- or EGF-induced phosphorylation of histone H3 at Ser28 was not affected by PD 98059, a MEK inhibitor, or SB 202190, a p38 kinase inhibitor, in MLTK-alpha-overexpressing JB6 Cl41 cells. Significantly, UVB- or EGF-induced phosphorylation of histone H3 at Ser28 was blocked by small interfering RNA of MLTK-alpha. The inhibition of histone H3 phosphorylation at Ser28 in the MLTK-alpha knock-down JB6 Cl41 cells was not due to a defect in mitogen- and stress-activated protein kinase 1 or 90-kDa ribosomal S6 kinase (p90RSK) activity. In summary, these results illustrate that MLTK-alpha plays a key role in the UVB- and EGF-induced phosphorylation of histone H3 at Ser28, suggesting that MLTK-alpha might be a new histone H3 kinase at the level of mitogen-activated protein kinase kinase kinases. PMID: [15684425] 

18. ERK and p38 MAP kinases, acting through the downstream mitogen- and stress-activated kinase 1/2 (MSK1/2), elicit histone H3 phosphorylation on a subfraction of nucleosomes--including those at Fos and Jun--concomitant with gene induction. S10 and S28 on the H3 tail have both been shown to be phospho-acceptors in vivo. Both phospho-epitopes appear with similar time-courses and both occur on H3 tails that are highly sensitive to TSA-induced hyperacetylation, similarities which might suggest that MSK1/2 phosphorylates both sites on the same H3 tails. Indeed, on recombinant histone octamers in vitro, MSK1 efficiently phosphorylates both sites on the same H3 tail. However, sequential immunoprecipitation studies show that antibodies against phosphorylated S10-H3 recover virtually all this epitope without depletion of phosphorylated S28-H3, and vice versa, indicating that the two phospho-epitopes are not located on the same H3 tail in vivo. Confocal immunocytochemistry confirms the clear physical separation of the two phospho-epitopes in the intact mouse nucleus. Finally, we used transfection-based experiments to test models that might explain such differential targeting. Overexpression and delocalisation of MSK1 does not result in the breakdown of targeting in vivo despite the fact that the ectopic kinase is fully activated by external stimuli. These studies reveal a remarkable level of targeting of S10 and S28 phosphorylation to distinct H3 tails within chromatin in the interphase mouse nucleus. Possible models for such exquisite targeting are discussed. PMID: [15870105] 

19. The Ras-mitogen activated protein kinase (Ras-MAPK) pathway plays an integral role in the formation of human malignancies. Stimulation of this pathway results in phosphorylation of histone H3 at serines 10 and 28 and expression of immediate-early genes. Phosphorylated (serine 10) H3, which is also acetylated on lysine 14, is associated with immediate-early genes. In this report, we investigated the relationship between these two H3 phosphorylation events in parental and ras-transformed fibroblasts. Immunoblot analyses of two-dimensional gel patterns demonstrated that all three H3 variants were phosphorylated after stimulation of the Ras-MAPK pathway and during mitosis. Following stimulation of the Ras-MAPK pathway, H3 phosphorylated on serines 10 and 28 was excluded from regions of highly condensed chromatin and was present in increased levels in ras-transformed cells. Although H3 phosphorylated at serine 10 or 28 was dynamically acetylated, H3 phosphorylated at serine 28 had a higher steady state of acetylation than that of H3 phosphorylated at serine 10. When visualized with indirect immunofluorescence, most foci of phosphorylated serine 28 H3 did not co-localize with foci of H3 phosphorylated on serine 10 or phosphoacetylated on serine 10 and lysine 14, suggesting that these two phosphorylation events act separately to promote gene expression. PMID: [15735677] 

20. Post-translational modifications (PTMs) of histones play an important role in many cellular processes, notably gene regulation. Using a combination of mass spectrometric and immunobiochemical approaches, we show that the PTM profile of histone H3 differs significantly among the various model organisms examined. Unicellular eukaryotes, such as Saccharomyces cerevisiae (yeast) and Tetrahymena thermophila (Tet), for example, contain more activation than silencing marks as compared with mammalian cells (mouse and human), which are generally enriched in PTMs more often associated with gene silencing. Close examination reveals that many of the better-known modified lysines (Lys) can be either methylated or acetylated and that the overall modification patterns become more complex from unicellular eukaryotes to mammals. Additionally, novel species-specific H3 PTMs from wild-type asynchronously grown cells are also detected by mass spectrometry. Our results suggest that some PTMs are more conserved than previously thought, including H3K9me1 and H4K20me2 in yeast and H3K27me1, -me2, and -me3 in Tet. On histone H4, methylation at Lys-20 showed a similar pattern as H3 methylation at Lys-9, with mammals containing more methylation than the unicellular organisms. Additionally, modification profiles of H4 acetylation were very similar among the organisms examined. PMID: [17194708] 

21. Histone lysine acetylation is a major mechanism by which cells regulate the structure and function of chromatin, and new sites of acetylation continue to be discovered. Here we identify and characterize histone H3K36 acetylation (H3K36ac). By mass spectrometric analyses of H3 purified from Tetrahymena thermophila and Saccharomyces cerevisiae (yeast), we find that H3K36 can be acetylated or methylated. Using an antibody specific to H3K36ac, we show that this modification is conserved in mammals. In yeast, genome-wide ChIP-chip experiments show that H3K36ac is localized predominantly to the promoters of RNA polymerase II-transcribed genes, a pattern inversely related to that of H3K36 methylation. The pattern of H3K36ac localization is similar to that of other sites of H3 acetylation, including H3K9ac and H3K14ac. Using histone acetyltransferase complexes purified from yeast, we show that the Gcn5-containing SAGA complex that regulates transcription specifically acetylates H3K36 in vitro. Deletion of GCN5 completely abolishes H3K36ac in vivo. These data expand our knowledge of the genomic targets of Gcn5, show H3K36ac is highly conserved, and raise the intriguing possibility that the transition between H3K36ac and H3K36me acts as an "acetyl/methyl switch" governing chromatin function along transcription units. PMID: [17189264] 

22. The RAG1 and RAG2 proteins are the only lymphoid-specific factors required to perform the first step of V(D)J recombination, DNA cleavage. While the catalytic domain of RAG1, the core region, has been well characterized, the role of the noncore region in modulating chromosomal V(D)J recombination efficiency remains ill defined. Recent studies have highlighted the role of chromatin structure in regulation of V(D)J recombination. Here we show that RAG1 itself, through a RING domain within its N-terminal noncore region, preferentially interacts directly with and promotes monoubiquitylation of histone H3. Mutations affecting the RAG1 RING domain reduce histone H3 monoubiquitylation activity, decrease V(D)J recombination activity in vivo, reduce formation of both signal-joint and coding-joint products on episomal substrates, and decrease efficiency of V(D)J recombination at the endogenous IgH locus in lymphoid cells. The results reveal that RAG1-mediated histone monoubiquitylation activity plays a role in regulating the joining phase of chromosomal V(D)J recombination. PMID: [20122409]

Variant histone H3 which replaces conventional H3 in awide range of nucleosomes in active genes. Constitutes thepredominant form of histone H3 in non-dividing cells and isincorporated into chromatin independently of DNA synthesis.Deposited at sites of nucleosomal displacement throughouttranscribed genes, suggesting that it represents an epigeneticimprint of transcriptionally active chromatin. Nucleosomes wrapand compact DNA into chromatin, limiting DNA accessibility to thecellular machineries which require DNA as a template. Histonesthereby play a central role in transcription regulation, DNArepair, DNA replication and chromosomal stability. DNAaccessibility is regulated via a complex set of post-translationalmodifications of histones, also called histone code, andnucleosome remodeling.
