1/1000. Predicted molecular weight: 13 kDa.
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.
Expressed abundantly in lung, kidney and adrenal gland, but not in adult brain.
