ID1 Gene Information

HGNC symbol
ID1 
Aliases
bHLHb24; dJ857M17.1.2 
Common name
inhibitor of DNA binding 1, HLH protein 
Entrez Id
3397
Description
The protein encoded by this gene is a helix-loop-helix (HLH) protein that can form heterodimers with members of the basic HLH family of transcription factors. The encoded protein has no DNA binding activity and therefore can inhibit the DNA binding and transcriptional activation ability of basic HLH proteins with which it interacts. This protein may play a role in cell growth, senescence, and differentiation. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008].
