Background
The protein encoded by this gene is a helix-loop-helix (HLH) protein that can form heterodimers with other HLH proteins. However, the encoded protein lacks a basic DNA-binding domain and therefore inhibits the DNA binding of any HLH protein with which it interacts. [provided by RefSeq, Aug 2011],
Function
function:ID (inhibitor of DNA binding) HLH proteins lack a basic DNA-binding domain but are able to form heterodimers with other HLH proteins, thereby inhibiting DNA binding. ID-3 inhibits the binding of E2A-containing protein complexes to muscle creatine kinase E-box enhancer. May inhibit other transcription factors.,induction:By phorbol 12-myristate 13-acetate (PMA).,similarity:Contains 1 basic helix-loop-helix (bHLH) domain.,subunit:Interacts with COPS5 and COPS7A (By similarity). Homodimer, and heterodimer with other HLH proteins.,tissue specificity:Expressed abundantly in lung, kidney and adrenal gland, but not in adult brain.,
