The protein encoded by MYOZ2（myozenin 2） belongs to a family of sarcomeric proteins that bind to calcineurin, a phosphatase involved in calcium-dependent signal transduction in diverse cell types. These family members tether calcineurin to alpha-actinin at the z-line of the sarcomere of cardiac and skeletal muscle cells, and thus they are important for calcineurin signaling. Mutations in MYOZ2 cause cardiomyopathy familial hypertrophic type 16, a hereditary heart disorder.蛋白别名为：MYOZ2 C4orf5;基因ID为：51778；蛋白质ID:Q9NPC6
