Protein attributes

Sequence length	119 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

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.
Subunit structure	Interacts with COPS5 and COPS7A By similarity. Homodimer, and heterodimer with other HLH proteins.
Subcellular location	Nucleus.
Tissue specificity	Expressed abundantly in lung, kidney and adrenal gland, but not in adult brain.
Induction	By phorbol 12-myristate 13-acetate (PMA).
Sequence similarities	Contains 1 basic helix-loop-helix (bHLH) domain.
Sequence caution	The sequence CAA47360.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally shortened.
