Probability (GAS) of Function in Spermatogenesis |
0.7676323
The probability was calculated by GAS algorithm, ranging from 0 to 1. The closer it is to 1, the more possibly it functions in spermatogenesis. |

1. Monoclonal antibodies to subunits of bovine heart cytochrome c oxidase were prepared by immunizing mice with the isolated enzyme. The majority of antibody-producing cell lines were found to react with two different subunits of similar molecular mass, as shown by Western blotting and ELISA titrations with the HPLC-purified subunits. The affinities of the monoclonal antibodies to the subunits were determined by ELISA titrations with increasing concentrations of NH4SCN. Two monoclonal antibodies with a low affinity to subunit VIa had a high affinity to subunit VIc, whereas two other antibodies showed the same affinity to subunits VIIa and VIIb. The same affinity of monoclonal antibodies suggested an evolutionary relationship of subunits VIIa and VIIb, which was further supported by reactivity of these antibodies to subunits VIIa and VIIb of cytochrome c oxidase from different species and tissues. Also the evolutionary relationship between subunit VIa and VIc was shown by hybridization at low stringency of cDNAs for rat cytochrome c oxidase subunits VIc and VIa-h (heart-type), after amplification by the polymerase chain reaction, with a probe of VIa-l (liver-type).

2. 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]
3. 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.

4. Acetylation of proteins on lysine residues is a dynamic posttranslational modification that is known to play a key role in regulating transcription and other DNA-dependent nuclear processes. However, the extent of this modification in diverse cellular proteins remains largely unknown, presenting a major bottleneck for lysine-acetylation biology. Here we report the first proteomic survey of this modification, identifying 388 acetylation sites in 195 proteins among proteins derived from HeLa cells and mouse liver mitochondria. In addition to regulators of chromatin-based cellular processes, nonnuclear localized proteins with diverse functions were identified. Most strikingly, acetyllysine was found in more than 20% of mitochondrial proteins, including many longevity regulators and metabolism enzymes. Our study reveals previously unappreciated roles for lysine acetylation in the regulation of diverse cellular pathways outside of the nucleus. The combined data sets offer a rich source for further characterization of the contribution of this modification to cellular physiology and human diseases. PMID: [16916647]
