WebSep 6, 2012 · The myosin light-chain (MLC) proteins are also classed into two groups, the essential and regulatory light chains. This review will provide an overview of the roles the myosin proteins play in the developing heart and their potential to give rise to CHDs. The known molecular genetics in humans and animal models will be discussed. Myosin light chain kinase (MLCK) inhibitors are one of the few peptides that can cross the plasma membrane relatively quickly. Under stressful conditions, MLCK's in the human body promotes increased permeability of microvessels. It is thought that MLCK phosphorylates endothelial myosin, leading to cell contraction.
