Myogenic regulatory factors

From Wikipedia, the free encyclopedia

Myogenic regulatory factors are basic-helix-loop-helix (bHLH) transcription factors that regulate myogenesis: MyoD, Myf5, myogenin, and MRF4[1].

These proteins contain a conserved basic DNA binding domain that binds the E box DNA motif [2]. They dimerize with other HLH containing proteins through an HLH-HLH interaction[3].
