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. We attempted to isolate genes involved in neuronal differentiation from a cell line 2Y-3t newly established from a mouse cerebellum. 2Y-3t cells proliferate in serum-containing medium and differentiate into neurons in serum-free medium. We took a subtraction method to isolate genes differentially expressed in differentiated cells and 17 cDNA clones were isolated. Functions of 6 cDNA clones are unknown. No. 60 cDNA clone has 723 nucleotides encoding 240 amino acid residues. It contains two putative EF-hand motifs and a coiled-coil region at C terminal end. Expression of the clone was undetectable at embryonic stage and was increased in brain during development. In situ hybridization showed that the expression was observed predominantly in neurons, suggesting that the protein may play roles in the neuronal differentiation and function. PMID: [12270117]

Tissue Specificity
Highest expression in testis, followed byovary, kidney, cerebrum, cerebellum, heart, liver, and spleen. Inthe cerebrum and cerebellum, undetectable at embryonic stages,expression increases after birth up to adult stage. In adult CNS,detected in neurons of the cerebellum, cerebrum and hippocampusformation, including dentate gyrus and Cornu Ammonis, but not inthe white matter. In the testis, expressed in spermatocytes, butnot in spermatogonia nor in interstitial cells. In ovary, foundpredominantly in mural granulosa cells and those of the cumulusoophorus. In kidney, expressed in collecting ducts, but not inglomeruli. Not detected in skeletal muscle.
