Protein Domain : IPR001609

Type:  Domain Name:  Myosin head, motor domain
Description:  Muscle contraction is caused by sliding between the thick and thin filaments of the myofibril. Myosin is a major component of thick filaments and exists as a hexamer of 2 heavy chains [], 2 alkali light chains, and 2 regulatory light chains. The heavy chain can be subdivided into the N-terminal globular head and the C-terminal coiled-coil rod-like tail, although some forms have a globular region in their C-terminal. There are many cell-specific isoforms of myosin heavy chains, coded for by a multi-gene family []. Myosin interacts with actin to convert chemical energy, in the form of ATP, to mechanical energy []. The 3-D structure of the head portion of myosin has been determined [] and a model for actin-myosin complex has been constructed [].The globular head is well conserved, some highly-conserved regions possibly relating to functional and structural domains []. The rod-like tail starts with an invariant proline residue, and contains many repeats of a 28 residue region, interrupted at 4 regularly-spaced points known as skip residues. Although the sequence of the tail is not well conserved, the chemical character is, hydrophobic, charged and skip residues occuring in a highly ordered and repeated fashion [].
