| Function: | |
Muscle contraction. Myosin is a protein that binds to F-actin and has ATPase activity that is activated by F-actin. |
|
||
| Subunit: | |
Muscle myosin is a hexameric protein that consists of 2 heavy chain subunits (MHC), 2 alkali light chain subunits (MLC) and 2 regulatory light chain subunits (MLC-2). |
| Subcellular location: | |
Cytoplasm, myofibril. Note=Thick filaments of the myofibrils. |
| Domain: | |
The rodlike tail sequence is highly repetitive, showing cycles of a 28-residue repeat pattern composed of 4 heptapeptides, characteristic for alpha-helical coiled coils. |
| Domain: | |
Limited proteolysis of myosin heavy chain produces 1 light meromyosin (LMM) and 1 heavy meromyosin (HMM). HMM can be further cleaved into 2 globular subfragments (S1) and 1 rod-shaped subfragment (S2). {ECO:0000305}. |
| Similarity: | |
Belongs to the TRAFAC class myosin-kinesin ATPase superfamily. Myosin family. {ECO:0000305}. |
