Myoblast determination protein 1 (MYOD1)

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.
