developmental stage:Found in most early fetal tissues but not in the corresponding mature tissues.,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-2 may be an inhibitor of tissue-specific gene expression.,similarity:Contains 1 basic helix-loop-helix (bHLH) domain.,subunit:Heterodimer with other HLH proteins.,tissue specificity:Highly expressed in early fetal tissues, including those of the central nervous system.,
