Protein

Myoblast determination protein 1

Gene

Myod1

Organism
Rattus norvegicus (Rat)
Status
Reviewed - Annotation score: 4 out of 5- Protein inferred from homologyi

Functioni

Acts as a transcriptional activator that promotes transcription of muscle-specific target genes and plays a role in muscle differentiation. Together with MYF5 and MYOG, co-occupies muscle-specific gene promoter core region during myogenesis. Induces fibroblasts to differentiate into myoblasts. Interacts with and is inhibited by the twist protein. This interaction probably involves the basic domains of both proteins (By similarity).By similarity

Phosphorylated by CDK9. This phosphorylation promotes its function in muscle differentiation (By similarity).By similarity
Acetylated by a complex containing EP300 and PCAF. The acetylation is essential to activate target genes. Conversely, its deacetylation by SIRT1 inhibits its function (By similarity).By similarity
Ubiquitinated on the N-terminus; which is required for proteasomal degradation.By similarity
Methylation at Lys-104 by EHMT2/G9a inhibits myogenic activity.By similarity
