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.

Myosin light chain kinase (MLCK) is the key regulator of various forms of cell motility including endothelial and epithelial permeability in particular. One of the potential MLCK inhibitors to be used in humans is a membrane permeable peptide H-RKKYKYRRK-NH2 (L-PIK).
