Target Information

Members of the Id family of basic helix-loop-helix (bHLH) proteins include ID1, ID2, ID3, and ID4. They are ubiquitously expressed and dimerize with members of the class A and B HLH proteins. Due to the absence of the basic region, the resulting heterodimers cannot bind DNA, thus negatively regulating DNA binding of bHLH proteins.

ID1 inhibits DNA binding of E12 and Myo D, functioning to inhibit muscle-specific gene expression. During muscle cell differentiation, ID protein levels fall, allowing E12 and/or E47 to form heterodimers with Myo D and myogenin, activating myogenic differentiation. Expression of each ID protein is growth factor–dependent, and reduction of ID mRNA levels delays reentry of arrested cells into the cell cycle following growth factor stimulation.
