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 ...

Atrial Light Chain-2 (ALC-2) also known as Myosin regulatory light chain 2, atrial isoform (MLC2a) is a protein that in humans is encoded by the MYL7 gene. [5] [6] ALC-2 expression is restricted to cardiac muscle atria in healthy individuals, where it functions to modulate cardiac development and contractility.
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),
Myosin light chain pulls the actin stress fiber attached to the cadherin, resisting the force of the adjacent cell's cadherin. However, when the inward pulling force of the actin stress fiber becomes greater than the outward pulling force of the cell adhesion molecules due to an overactive MYLK, tissues can become slightly pulled apart and ...
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.
This gene, a muscle member of the immunoglobulin superfamily, encodes a myosin light-chain kinase, which is a calcium-/calmodulin-dependent enzyme.This kinase phosphorylates myosin regulatory light chains to facilitate myosin interaction with actin filaments to produce contractile activity.
The two types of light chains are kappa (κ) and lambda (λ). By cleavage with enzyme papain, the Fab (fragment-antigen binding) part can be separated from the Fc (fragment crystallizable region) part of the molecule. The Fab fragments contain the variable domains, which consist of three antibody hypervariable amino acid domains responsible for ...
