Abstract of related literatures
1. 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] 

2. 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.

3. The group-specific component (GC), also known as the vitamin D-binding protein, transports vitamin D and its metabolites in plasma to target tissues throughout the body. The GC gene shares an evolutionary origin with genes encoding albumin (ALB) and alpha-fetoprotein (AFP). All three genes are descendants of an evolutionary ancestor that arose from an intragenic triplication. As a result, each gene is composed of three homologous domains. The study described here characterizes and compares mouse GC to the corresponding nucleotide and amino acid sequences of GC from human and rat. The deduced amino acid sequence of mouse GC was 78% identical to human and 91% identical to rat GC. The results suggest that, unlike the corresponding sequences in the ALB and AFP genes, chromosomal sequences encoding the first domain and the leader sequence of the GC gene have specifically been conserved throughout vertebrate evolution. Protection of domain I during evolution may correlate with an important functional aspect of its sequence. The mouse GC gene was mapped to chromosome 5, where the ALB and AFP genes are also located, demonstrating conservation of the three genes in vertebrate species. PMID: [1696927] 

4. 1. In order to establish a homologous system in which to study the interaction of mouse vitamin D-binding protein (MVDBP) with mouse T-cell lymphocytes, we purified MVDBP from mouse plasma. 2. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) showed that purified MVDBP had an apparent relative molecular weight of 49,000. 3. Previous work in our laboratory has shown that purified rat vitamin D-binding protein (RVDBP) has an apparent relative molecular weight of 52,000. 4. The amino terminal amino acid sequence of MVDBP is shown below and compared with that of RVDBP. MVDBP: LeuGluArgGlyArgAspTyrGluLysAspLysValCysAsnGluLeuAlaMetLeuGlyLysGlu RVDBP: LeuGluArgGlyArgAspTyrGluLysAspLysValCysGlnGluLeuSerThrLeuGlyLysAsp AspPhe AspPhe While 21 out of 24 residues (87.5%) of the amino terminus of MVDBP are the same as those in RVDBP, residues 14, 17, 18 and 22 (underlined) are different. 5. The sedimentation coefficient of the protein, determined by sucrose density gradient ultracentrifugation, is 3.8 for MVDBP and 4.1 for the rat VDBP. 6. The MVDBP purified in this study exhibits only one isoform on isoelectric focusing; the isoelectric point was 4.87 as determined on pH 4.0-6.5 isoelectric focusing gels (IEF). 7. The binding of vitamin D3, 25-hydroxyvitamin D3 and three other analogs was investigated with a charcoal dextran assay.(ABSTRACT TRUNCATED AT 250 WORDS) PMID: [3243374] 

5. A comprehensive understanding of the mouse plasma proteome is important for studies using mouse models to identify protein markers of human disease. To enhance our analysis of the mouse plasma proteome, we have developed a method for isolating low-abundance proteins using a cysteine-containing glycopeptide strategy. This method involves two orthogonal affinity capture steps. First, glycoproteins are coupled to an azlactone copolymer gel using hydrazide chemistry and cysteine residues are then biotinylated. After trypsinization and extensive washing, tethered N-glycosylated tryptic peptides are released from the gel using PNGase F. Biotinylated cysteinyl-containing glycopeptides are then affinity selected using a monomeric avidin gel and analyzed by LC-MS/MS. We have applied the method to a proteome analysis of mouse plasma. In two independent analyses using 200 muL each of C57BL mouse plasma, 51 proteins were detected. Only 42 proteins were seen when the same plasma sample was analyzed by glycopeptides only. A total of 104 N-glycosylation sites were identified. Of these, 17 sites have hitherto not been annotated in the Swiss-Prot database whereas 48 were considered probable, potential, or by similarity - i.e., based on little or no experimental evidence. We show that analysis by cysteine-containing glycopeptides allows detection of low-abundance proteins such as the epidermal growth factor receptor, the Vitamin K-dependent protein Z, the hepatocyte growth factor activator, and the lymphatic endothelium-specific hyaluronan receptor as these proteins were not detected in the glycopeptide control analysis.

Function
Multifunctional protein found in plasma, ascitic fluid,cerebrospinal fluid, and urine and on the surface of many celltypes. In plasma, it carries the vitamin D sterols and preventspolymerization of actin by binding its monomers. DBP associateswith membrane-bound immunoglobulin on the surface of B-lymphocytesand with IgG Fc receptor on the membranes of T-lymphocytes.
