General description

Myosin light chain kinase (MLCK) comprises an N-terminal actin-binding domain, a central kinase domain, and a C-terminal myosin-binding domain.

Application

Myosin Light Chain Kinase Substrate (smooth muscle) has been used in MLCK activity assay to study the role of Plasmodium falciparum calmodulin (Pf CaM).

Biochem/physiol Actions

KKRAARATSNVFA-NH2 is used as a myosin light chain kinase (MLCK) substrate.
Myosin light chain kinase (MLCK) is involved in modulating the actin-myosin interaction of smooth muscle. In addition to its kinase activity, MLCK also has actin-binding activity, which can assemble actin filaments into bundles. It also has myosin-binding activity, which can generate myosin filaments.
