[https://www.uniprot.org/uniprot/MYOD1_MOUSE MYOD1_MOUSE] 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.<ref>PMID:3175662</ref>

==Overview==
    <scriptWhenUnchecked>script /wiki/extensions/Proteopedia/spt/initialview01.spt</scriptWhenUnchecked>
The crystal structure of a MyoD basic-helix-loop-helix (bHLH) domain-DNA complex has been solved and refined at 2.8 A resolution. This structure proves that bHLH and bHLH-leucine zipper (bHLH-ZIP) proteins are remarkably similar; it helps us understand subtle differences in binding preferences for these proteins; and it has surprising implications for our understanding of transcription. Specifically, Ala-114 and Thr-115, which are required for positive control in the myogenic proteins, are buried at the protein-DNA interface. These residues are not available for direct protein-protein contacts, but they may determine the conformation of Arg-111. Comparisons with Max suggest that the conformation of this arginine, which is different in the two structures, may play an important role in myogenic transcription.
