MEF2A: Proteins and Enzymes

MEF2A (myocyte specific enhancer factor 2) is a transcription factor protein that belongs to MEF2 family, a family of DNA binding regulatory proteins. MEF2 family members (MEF2A, 2B, 2C, and 2D) are highly expressed during dendritic maturation and synapse formation in the brain and are involved in the regulation of development and function of T-cell, muscle cells, and brain cells (1). Highly expressed during synaptogenesis, MEF2A binds to MEF2 element present in the regulatory regions in various muscle specific genes and activates transcription. MEF2A has been implicated in cardiac and skeletal muscle development (2).
