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]
A study in human menstrual blood-derived mesenchymal stem cells (MenSCs) demonstrated that the ID1 gene is overexpressed in cells from women with endometriosis and plays an important role in inflammation associated with the disease, interacting with TNFA and hypoxia signaling pathways [Penariol et al.
