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
MEF2B_HUMAN Transcriptional activator which binds specifically to the MEF2 element, 5'-YTA[AT](4)TAR-3', found in numerous muscle-specific genes. Activates transcription via this element.
