Myogenic regulatory factors
Group of proteins regulating myogenesis / From Wikipedia, the free encyclopedia
Myogenic regulatory factors (MRF) 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]
