General annotation (Comments)

Function

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 By similarity.

Subunit structure

Myosin is a hexamer of 2 heavy chains and 4 light chains By similarity.

Post-translational modification

Phosphorylation increases the actin-activated myosin ATPase activity and thereby regulates the contractile activity. It is required to generate the driving force in the migration of the cells but not necessary for localization of myosin-2 at the leading edge By similarity.

Miscellaneous

This chain binds calcium By similarity.

Sequence similarities

Contains 3 EF-hand domains.
