WebOct 7, 2024 · October 7, 2024 by Carrie V. MLCK is a myosin light chain kinase that is responsible for phosphorylating myosin light chains. This phosphorylation is necessary for muscle contraction. MLCK is found in all muscle tissues, including smooth muscle. Smooth muscle contraction is important for many physiological processes, including blood … WebMyosin light chains (MLCs) can be broadly classified into two groups: Essential or alkali MLC (MLC1 or ELC), Regulatory MLC (MLC2 or RLC). Essential and regulatory MLCs have molecular masses of 22 and 19 kDa, respectively. Structurally, MLC2 contains a serine residue that is lacking in MLC1.
