Mol. Cell. Cardiol. 35:841-849(2003). CC -!- SUBUNIT: Myosin is an hexamer of 2 heavy chains and 4 light CC chains. CC -!- INTERACTION: CC P35125:USP6; NbExp=2; IntAct=EBI-725770, EBI-954564; CC -!- PTM: N-terminus is methylated by METTL11A/NTM1 (By similarity). CC -!- DISEASE: Defects in MYL2 are the cause of cardiomyopathy familial CC hypertrophic type 10 (CMH10) [MIM:608758]. Familial hypertrophic CC cardiomyopathy is a hereditary heart disorder characterized by CC ventricular hypertrophy, which is usually asymmetric and often CC involves the interventricular septum. The symptoms include CC dyspnea, syncope, collapse, palpitations, and chest pain. They can CC be readily provoked by exercise. The disorder has inter- and CC intrafamilial variability ranging from benign to malignant forms CC with high risk of cardiac failure and sudden cardiac death. CC -!- DISEASE: Defects in MYL2 are the cause of cardiomyopathy familial CC hypertrophic with mid-left ventricular chamber type 2 (MVC2) CC [MIM:608758]. MVC2 is a very rare variant of familial hypertrophic CC cardiomyopathy, characterized by mid-left ventricular chamber CC thickening. CC -!- MISCELLANEOUS: This chain binds calcium. CC -!- SIMILARITY: Contains 3 EF-hand domains.
