Myosin-9; During cell spreading, plays an important role in cytoskeleton reorganization, focal contacts formation (in the margins but not the central part of spreading cells), and lamellipodial retraction; this function is mechanically antagonized by MYH10 (By similarity). Cellular myosin that appears to play a role in cytokinesis, cell shape, and specialized functions such as secretion and capping; Belongs to the TRAFAC class myosin-kinesin ATPase superfamily. Myosin family.

Myosin-11; Muscle contraction; Belongs to the TRAFAC class myosin-kinesin ATPase superfamily. Myosin family.

Myosin, light chain 12A, regulatory, non-sarcomeric.

Myosin regulatory light chain 12B; Myosin regulatory subunit that plays an important role in regulation of both smooth muscle and nonmuscle cell contractile activity via its phosphorylation. Phosphorylation triggers actin polymerization in vascular smooth muscle. Implicated in cytokinesis, receptor capping, and cell locomotion.

Myosin regulatory light polypeptide 9; Myosin regulatory subunit that plays an important role in regulation of both smooth muscle and nonmuscle cell contractile activity via its phosphorylation. Implicated in cytokinesis, receptor capping, and cell locomotion.

Myosin light polypeptide 6; Regulatory light chain of myosin. Does not bind calcium.

Myosin light chain kinase 2, skeletal/cardiac muscle; Implicated in the level of global muscle contraction and cardiac function. Phosphorylates a specific serine in the N-terminus of a myosin light chain (By similarity).

Myosin light chain kinase 3; Kinase that phosphorylates MYL2 in vitro. Has been proposed to be calmodulin-dependent , although MYL2 phosphorylation has also been observed in the presence or absence of calmodulin. Promotes sarcomere formation in cardiomyocytes and increases cardiomyocyte contractility. Belongs to the protein kinase superfamily. CAMK Ser/Thr protein kinase family.

Myosin regulatory light chain 2, ventricular/cardiac muscle isoform; Contractile protein that plays a role in heart development and function. Following phosphorylation, plays a role in cross-bridge cycling kinetics and cardiac muscle contraction by increasing myosin lever arm stiffness and promoting myosin head diffusion; as a consequence of the increase in maximum contraction force and calcium sensitivity of contraction force. These events altogether slow down myosin kinetics and prolong duty cycle resulting in accumulated myosins being cooperatively recruited to actin binding sites t [...]
