  • 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.
  • Sequence similarities
    Contains 1 basic helix-loop-helix (bHLH) domain.
  • Developmental stage
    Expression correlates with proliferation in some types of cells.
  • Cellular localization
    Cytoplasm. Nucleus.
