MyoD

Evidence suggests that Setdb1 inhibits a repressor of MyoD and this is the mechanism through which MyoD expression is retained in differentiated myoblasts.
MyoD works with a transient placeholder protein that functions to prevent other transcription factors from binding to the DNA and also retains an inactive conformation for the DNA. Once the placeholder is removed (or possibly deactivated) the necessary transcription factors are free to bind and initiate recruitment of RNA Polymerase II and initiate active RNA transcription.

MyoD is a protein that plays a major role in regulating muscle differentiation. MyoD, which was discovered in the laboratory of Harold M. Weintraub, belongs to a family of proteins known as myogenic regulatory factors (MRFs). These bHLH (basic helix loop helix) transcription factors act sequentially in myogenic differentiation. MRF family members include MyoD, Myf5, myogenin, and MRF4 (Myf6).
