The myocyte enhancer factor-2 (MEF2) binding domain, predominantly found in the calcineurin-binding protein CABIN 1, adopts an amphipathic alpha-helical structure, which allows it to bind a hydrophobic groove on the MEF2S domain, forming a triple-helical interaction. Interaction of this domain with MEF2 causes repression of transcription [1].	Domain
