Myosin light chain phosphatase action
Structurally, myosin light chains belong to the EF-hand family, a large family of Ca - binding proteins. MLCs contain two Ca - binding EF-hand motifs. MLCs isoforms modulate the Ca of force transduction and cross-bridge kinetics. Myosin light chains (MLCs) can be broadly classified into two groups: • Essential or alkali MLC (MLC1 or ELC), [myosin light-chain] phosphate + H 2 O = [myosin light-chain] + phosphate This dephosphorylation reaction occurs in smooth muscle tissue and initiates the relaxation process of the muscle cells. Thus, myosin phosphatase undoes the muscle contraction process initiated by myosin light-chain kinase . See more Myosin light-chain phosphatase, also called myosin phosphatase (EC 3.1.3.53; systematic name [myosin-light-chain]-phosphate phosphohydrolase), is an enzyme (specifically a serine/threonine-specific protein phosphatase See more Myosin phosphatase is made of three subunits. The catalytic subunit, PP1, is one of the more important Ser/Thr phosphatases in See more The regulatory pathways of MLC kinase have been well-established, but until the late 1980s, it was assumed that myosin phosphatase was not regulated, and contraction/relaxation was entirely dependent on MLC kinase activity. However, since the … See more • Pato MD, Adelstein RS (1983). "Purification and characterization of a multisubunit phosphatase from turkey gizzard smooth muscle. The effect of calmodulin binding to myosin light chain kinase on dephosphorylation" See more Smooth muscle tissue is mostly made of actin and myosin, two proteins that interact together to produce muscle contraction and relaxation. Myosin II, also known as conventional myosin, has two heavy chains that consist of the head and tail domains and four … See more The mechanism of removing the phosphate from Ser-19 is very similar to other dephosphorylation reactions in the cell, such as the activation of glycogen synthase.
