PROTEIN

PHYSICAL PROPERTIES

STRUCTURE

motifs/domains	globular head associating to the light chain (amino acid residues &
	8764;1–779)
	actin and ATP binding sites
	a neck containing IQ calmodulin or calmodulin-like light binding domain (the converter) connected to the base of a long alpha helical tail, rodlike tail sequence highly repetitive, showing cycles of a 28-residue repeat pattern composed of 4 heptapeptides, characteristic for alpha-helical coiled coils
	a myosin head-like domain
	globular motor domain (AAs &
	8764;1–779) attached by short neck (&
	8764;779–840) and hinge (&
	8764;840) regions to a long coiled-coil rod domain (&
	8764;840–1,940)
	majority of the rod region comprises the myosin tail domain (AAs &
	8764;1,070–1,940)

HOMOLOGY

Homologene

FAMILY

CATEGORY

motor/contractile

SUBCELLULAR LOCALIZATION	intracellular
	intracellular,cytoplasm,cytosolic
text	in thick filaments of the myofibrils

basic FUNCTION	motor contractile protein moving towards the "plus" end of actin track
	involved in muscle contraction
	plays a crucial role in important processes in the early developing heart and, hence, is a candidate causative gene for atrial septal defects and cardiomyopathy
	protein that assembles as homo- and hetero-dimers to form the thick filament in the sarcomere
