Myogenin (myogenic factor 4), also known as MYOG, is a gene.[1]

Myogenin is a muscle-specific basic-helix-loop-helix (bHLH) transcription factor involved in the coordination of skeletal muscle development or myogenesis and repair. Myogenin is a member of the MyoD family of transcription factors, which also includes MyoD, Myf5, and Mrf4.

In mice, myogenin is essential for the development of functional skeletal muscle. Myogenin is required for the fusion of myogenic precursor cells to either new or previously existing fibers during the process of differentiation in myogenesis. When the DNA coding for myogenin was knocked out of the mouse genome, severe skeletal muscle defects were observed. Mice lacking both copies of myogenin (homozygous-null) suffer from perinatal lethality due to the lack of mature secondary skeletal muscle fibers throughout the body.

In cell culture, myogenin can induce myogenesis in a variety of non-muscle cell types.

Interactions[edit]

Myogenin has been shown to interact with POLR2C,[2] Sp1 transcription factor,[3] TCF3,[4][5] Serum response factor[3][6] and MDFI.[7]
