CC   -!- FUNCTION: Muscle contraction. {ECO:0000305}.
CC   -!- SUBUNIT: Muscle myosin is a hexameric protein that consists of 2 heavy
CC       chain subunits (MHC), 2 alkali light chain subunits (MLC) and 2
CC       regulatory light chain subunits (MLC-2). {ECO:0000305}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm, myofibril. Note=Thick filaments of the
CC       myofibrils. {ECO:0000305}.
CC   -!- DOMAIN: Limited proteolysis of myosin heavy chain produces 1 light
CC       meromyosin (LMM) and 1 heavy meromyosin (HMM). HMM can be further
CC       cleaved into 2 globular subfragments (S1) and 1 rod-shaped subfragment
CC       (S2). {ECO:0000305}.
