Mus musculus gene Epas1, encoding endothelial PAS domain protein 1.
SUMMARY back to top
RefSeq annotates one representative transcript (NM included in AceView variant.a), but Mus musculus cDNA sequences in GenBank, dbEST, Trace and SRA, filtered against clone rearrangements, coaligned on the genome and clustered in a minimal non-redundant way by the manually supervised AceView program, support at least 2 spliced variants.

AceView synopsis, each blue text links to tables and details
Expression: According to AceView, this gene is expressed at high level, 1.6 times the average gene in this release. The sequence of this gene is defined by 165 GenBank accessions from 148 cDNA clones, some from inner ear (seen 5 times), brain (3), diencephalon (3), heart (3), kidney (3), lung (3), whole embryo including extraembryonictissues at 11.5-days postcoitum (3) and 26 other tissues. We annotate structural defects or features in 5 cDNA clones.
Alternative mRNA variants and regulation: The gene contains 15 distinct gt-ag introns. Transcription produces 4 different mRNAs, 2 alternatively spliced variants and 2 unspliced forms. The mRNAs appear to differ by truncation of the 5' end, overlapping exons with different boundaries. 473 bp of this gene are antisense to spliced gene sikiro, raising the possibility of regulated alternate expression.
Function: There are 52 articles specifically referring to this gene in PubMed. Functionally, the gene has been tested for association to diseases (cardiovascular system phenotype; hematopoietic system phenotype; homeostasis/metabolism phenotype; immune system phenotype; lethality-embryonic/perinatal), proposed to participate in pathway (Renal cell carcinoma) and processes (angiogenesis, blood vessel remodeling, cardiac chronotropy, cell differentiation, cell maturation, embryonic placenta development, erythrocyte differentiation, hemopoiesis, lung development, mitochondrion organization and biogenesis, norepinephrine metabolic process, positive regulation of transcription from RNA polymerase II promoter, regulation of transcription from RNA polymerase II promoter in response to oxidative stress, response to hypoxia, surfactant homeostasis, visual perception, multicellular organismal development, regulation of transcription, DNA-dependent, signal transduction, two-component signal transduction system (phosphorelay)). Proteins are expected to have molecular functions (DNA binding, protein heterodimerization activity, transcription factor activity, transcription factor binding, protein binding, signal transducer activity, transcription regulator activity, two-component sensor activity) and to localize in various compartments (cytoplasm, nucleus, transcription factor complex).
Please see the Jackson Laboratory Mouse Genome Database/Informatics site MGI_109169 for in depth functional annotation of this gene.
Protein coding potential: The 2 spliced and 2 unspliced mRNAs putatively encode good proteins, altogether 4 different isoforms (2 complete, 2 partial), some containing domains basic helix-loop-helix dimerisation region bHLH, PAS fold-3 [Pfam].

Exon size is proportional to length, intron height reflects the number of cDNAs supporting each intron, the small numbers show the support of the introns in deep sequencing (with details in mouse-over) . Introns of the same color are identical, of different colors are different. 'Good proteins' are pink, partial or not-good proteins are yellow, uORFs are green. 5' cap or3' poly A flags show completeness of the transcript.
