Summary

Official Symbol: Bhlhe40provided by RGD
Official Full Name: basic helix-loop-helix family, member e40provided by RGD
Primary source: RGD:68439

Gene type: protein coding
RefSeq status: PROVISIONAL

Lineage: Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Glires; Rodentia; Myomorpha; Muroidea; Muridae; Murinae; Rattus
Also known as: Dec1; Bhlhb2; Sharp2; Stra13; Stra14; SHARP-2
Summary: This gene encodes a basic helix-loop-helix protein expressed in various tissues. The encoded protein can interact with Arntl or compete for E-box binding sites in the promoter of Per1 and repress Clock/Arntl's transactivation of Per1. This gene is believed to be involved in the control of circadian rhythm and cell differentiation. [provided by RefSeq, Feb 2014]
Expression: Biased expression in Muscle (RPKM 282.3), Kidney (RPKM 211.4) and 9 other tissues See more

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
