Myosin light chain 20

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), WebFeb 9, 2006 · Victor A. McKusick - updated : 4/20/1999 Creation Date: Victor A. McKusick : 6/2/1986 ... Muscle myosin is a heterohexamer consisting of 2 myosin heavy chains and 2 associated nonidentical pairs of myosin light chains.

WebMyosin light chain phosphatase (MLCP) catalyzes the dephosphorylation of the RLCs. Dephosphorylating the RLCs of myosin inhibits myosin cross-bridge formation with actin, but dephosphorylating myosin already on actin reduces its off rate, forming the so-called “latch state.” ... The myosin lever arm and its RLC 20 is a major intersection ... It also contains 4 myosin light chains (MLC), resulting in 2 per head, weighing 20 (MLC 20) and 17 (MLC 17) kDa. These bind the heavy chains in the "neck" region between the head and tail. The MLC 20 is also known as the regulatory light chain and actively participates in muscle contraction . See more Myosins are a superfamily of motor proteins best known for their roles in muscle contraction and in a wide range of other motility processes in eukaryotes. They are ATP-dependent and responsible for actin-based motility.
