Probability (GAS) of Function in Spermatogenesis |
0.165650205 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. A mouse kidney cDNA isolated by differential screening was found to be highly homologous to rat, human, and bovine plasma glutathione peroxidase (GPx) sequences. Analysis of the full-length coding region sequence demonstrated an in-frame selenocysteine-encoding opal codon and putative signal sequence, suggesting that the sequence represents the mouse homolog of plasma GPx. The level of expression of plasma GPx in various mouse tissues and during development was investigated by Northern blot analysis. Plasma GPx mRNA was observed to be very abundant in kidney compared with placenta, epididymis, intestine, lung, heart, testis, ovary, salivary gland, spleen, thymus, stomach, brain, and fetal kidney and could not be detected in pancreas or in liver except from pregnant mice. In addition, plasma GPx mRNA levels were shown to increase during postnatal development of the kidney. In situ hybridization localized plasma GPx mRNA to proximal tubules, while primary cell culture demonstrated that plasma GPx is synthesized and secreted by proximal tubular epithelial cells. The relative abundance of plasma GPx mRNA in mouse kidney suggests that proximal tubules may be the primary source of the enzyme detectable in plasma and further suggests that plasma GPx has an important function in protecting the kidney from oxidative damage.

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. Using a reverse transcription coupled to PCR amplification strategy, with degenerated primers localized in highly conserved domains of known glutathione peroxidase (GPX) proteins, we have generated, from mouse epididymal RNA, a cDNA fragment which was subsequently used to isolate a genomic clone encoding mouse plasma GPX (GPX3). GPX3 is a major enzyme in reducing lipid hydroperoxides and hydrogen peroxide in plasma. We confirm here that the mouse epididymis is a new site of expression of GPX3 and report, together with the sequence, the structural analysis and the chromosomal localization of the mouse GPX3 single-copy gene to chromosome 11.
