Class C basic helix-loop-helix protein 1, MYF3, Myod 1, MYOD1, Myogenic differentiation 1, PUM,
Involved in muscle differentiation (myogenic factor). Induces fibroblasts to differentiate into myoblasts. Activates muscle-specific promoters. Interacts with and is inhibited by the twist protein. This interaction probably involves the basic domains of both proteins.
