CRYSTAL STRUCTURE OF MEF2A CORE BOUND TO DNACRYSTAL STRUCTURE OF MEF2A CORE BOUND TO DNA

Structural highlights

1egw is a 8 chain structure with sequence from Homo sapiens. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Method:X-ray diffraction, Resolution 1.5Å
Resources:FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT

Disease

MEF2A_HUMAN Defects in MEF2A are a cause of coronary artery disease, autosomal dominant, type 1 (ADCAD1) [MIM:608320. A common heart disease characterized by reduced or absent blood flow in one or more of the arteries that encircle and supply the heart. Its most important complication is acute myocardial infarction.

Function

MEF2A_HUMAN Transcriptional activator which binds specifically to the MEF2 element, 5'-YTA[AT](4)TAR-3', found in numerous muscle-specific genes. Also involved in the activation of numerous growth factor- and stress-induced genes. Mediates cellular functions not only in skeletal and cardiac muscle development, but also in neuronal differentiation and survival. Plays diverse roles in the control of cell growth, survival and apoptosis via p38 MAPK signaling in muscle-specific and/or growth factor-related transcription. In cerebellar granule neurons, phosphorylated and sumoylated MEF2A represses transcription of NUR77 promoting synaptic differentiation.[1] [2] [3] [4] [5] [6] [7]
