Myosin_tail_1

Myosin_tail_1
PFAM accession number:PF01576
Interpro abstract (IPR002928):

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 [(PUBMED:1939027)], 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 [(PUBMED:2806546)]. Myosin interacts with actin to convert chemical energy, in the form of ATP, to mechanical energy [(PUBMED:3540939)]. The 3-D structure of the head portion of myosin has been determined [(PUBMED:8316857)] and a model for actin-myosin complex has been constructed [(PUBMED:8316858)].

This family consists of the coiled-coil myosin heavy chain tail region. The coiled-coil is composed of the tail from two molecules of myosin. These can then assemble into the macromolecular thick filament [(PUBMED:3783701)]. The coiled-coil region provides the structural backbone of the thick filament [(PUBMED:3783701)].
