MeSH Heading: Myosin-Light-Chain Kinase
Tree Number(s): D08.811.913.696.620.682.700.125.500; D12.776.476.563.125.500
Unique ID: D009219
RDF Unique Identifier: http://id.nlm.nih.gov/mesh/D009219
Scope Note: An enzyme that phosphorylates myosin light chains in the presence of ATP to yield myosin-light chain phosphate and ADP, and requires calcium and CALMODULIN. The 20-kDa light chain is phosphorylated more rapidly than any other acceptor, but light chains from other myosins and myosin itself can act as acceptors. The enzyme plays a central role in the regulation of smooth muscle contraction.
