Structurally, myosin light chains belong to the EF-hand family, a large family of Ca 2+ - binding proteins. MLCs contain two Ca 2+ - binding EF-hand motifs. MLCs isoforms modulate the Ca 2+ 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),
In smooth muscle, a single gene [20]) codes for the heavy chains myosin II, but splice variants of this gene result in four distinct isoforms. [19] It also contains 4 myosin light chains (MLC), resulting in 2 per head, weighing 20 (MLC 20) and 17 (MLC 17) kDa. [19] These bind the heavy chains in the "neck" region between the head and tail.
Myosin regulatory light chain 2, ventricular/cardiac muscle isoform (MLC-2) also known as the regulatory light chain of myosin (RLC) is a protein that in humans is encoded by the MYL2 gene. [ 5 ] [ 6 ] This cardiac ventricular RLC isoform is distinct from that expressed in skeletal muscle ( MYLPF ), smooth muscle ( MYL12B ) and cardiac atrial ...

Cardiac, ventricular ELC is 21.9 kDa and composed of 195 amino acids (See human MYL3 sequences features here Archived 2015-09-24 at the Wayback Machine).Cardiac ELC and the second light chain, regulatory light chain (RLC, MYL2), are non-covalently bound to IQXXXRGXXXR motifs in the 9 nm S1-S2 lever arm of the myosin head, [8] both alpha and beta isoforms.
Myosin light chain 6B is a protein that in humans is encoded by the MYL6B gene. [5] [6] [7] Myosin is a hexameric ATPase cellular motor protein.It is composed of two heavy chains, two nonphosphorylatable alkali light chains, and two phosphorylatable regulatory light chains.
Myosin light polypeptide 6 is a protein that in humans is encoded by the MYL6 gene. [5] [6] [7] [8]Myosin is a hexameric ATPase cellular motor protein.It is composed of two heavy chains, two nonphosphorylatable alkali light chains, and two phosphorylatable regulatory light chains.
Myosin II is an elongated protein that is formed from two heavy chains with motor heads and two light chains. Each myosin head contains actin and ATP binding site. The myosin heads bind and hydrolyze ATP, which provides the energy to walk toward the plus end of an actin filament. Myosin II are also vital in the process of cell division. For ...
