1. Introduction. Myocyte enhancer factor 2 is an important family of transcription factors comprised of four members, MEF2A-D. These have an almost identical N-terminus (amino acids (aa) 1-86), but distinct C-termini (Figure 1A).The N-terminus has a MADS (MCM1, Agamous, Deficiens and Serum response factor) domain (aa 2-57) followed by a MEF2-specific domain (aa 58-86).
