研究背景
The protein encoded by this gene 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 this gene cause cardiomyopathy familial hypertrophic type 16, a hereditary heart disorder. [provided by RefSeq, Aug 2011],function:Myozenins may serve as intracellular binding proteins involved in linking Z-disk proteins such as alpha-actinin, gamma-filamin, TCAP/telethonin, LDB3/ZASP and localizing calcineurin signaling to the sarcomere. Plays an important role in the modulation of calcineurin signaling. May play a role in myofibrillogenesis.,similarity:Belongs to the myozenin family.,subcellular location:Colocalizes with ACTN1 and PPP3CA at the Z-line of heart and skeletal muscle.,subunit:Interacts via its C-terminus with spectrin repeats 3 and 4 of ACTN2. Interacts with ATCN1, LDB3, MYOT and PPP3CA.,tissue specificity:Expressed specifically in heart and skeletal muscle.,
