CRYSTAL STRUCTURE OF MYOD BHLH DOMAIN BOUND TO DNA: PERSPECTIVES ON DNA RECOGNITION AND IMPLICATIONS FOR TRANSCRIPTIONAL ACTIVATION

Structural highlights

1mdy is a 8 chain structure with sequence from Mus musculus. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Resources:	FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT

Function

[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.^[1]

Evolutionary Conservation

Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf.

Publication Abstract from PubMed

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.
