Protein-coding gene in the species Homo sapiens
Myocyte-specific enhancer factor 2A is a
protein that in humans is encoded by the MEF2A
gene .
[5]
[6] MEF2A is a
transcription factor in the
Mef2 family. In humans it is located on
chromosome 15q26 . Certain
mutations in MEF2A cause an
autosomal dominant form of
coronary artery disease and
myocardial infarction .
Function
The process of differentiation from mesodermal precursor cells to myoblasts has led to the discovery of a variety of tissue-specific factors that regulate muscle gene expression. The myogenic basic helix-loop-helix proteins, including myoD (MIM 159970), myogenin (MIM 159980), MYF5 (MIM 159990), and MRF4 (MIM 159991) are 1 class of identified factors. A second family of DNA binding regulatory proteins is the myocyte-specific enhancer factor-2 (MEF2) family. Each of these proteins binds to the MEF2 target DNA sequence present in the regulatory regions of many, if not all, muscle-specific genes. The MEF2 genes are members of the MADS gene family (named for the yeast mating type-specific transcription factor MCM1, the plant homeotic genes 'agamous' and 'deficiens' and the human serum response factor SRF (MIM 600589)), a family that also includes several homeotic genes and other transcription factors, all of which share a conserved DNA-binding domain.[supplied by OMIM]
