We now show that an analogous cell-cycle-regulated phosphorylation of Id3 alters the specificity of Id3 for abrogating both E-box-dependent bHLH homo- or heterodimer complex formation in vitro and E-box-dependent reporter gene function in vivo.
 protein: E-box-dependent bHLH; DNA: reporter gene; protein: Id3; protein: Id3
