Mutations of ventricular essential myosin light chain disturb myosin binding and sarcomeric sorting.
AIMS We tested the hypothesis that mutations in the human ventricular essential myosin light chain (hVLC-1) that are associated with hypertrophic cardiomyopathy (HCM) affect protein structure, binding to the IQ1 motif of cardiac myosin heavy chain (MYH) and sarcomeric sorting in neonatal cardiomyocytes. METHODS AND RESULTS We employed circular dichroism and surface plasmon resonance spectrosc...
متن کاملMyosin light-chain kinase of smooth muscle stimulates myosin ATPase activity without phosphorylating myosin light chain.
Myosin light-chain kinase (MLCK) of smooth muscle is multifunctional, being composed of N-terminal actin-binding domain, central kinase domain, and C-terminal myosin-binding domain. The kinase domain is the best characterized; this domain activates the interaction of smooth-muscle myosin with actin by phosphorylating the myosin light chain. We have recently shown that the Met-1-Pro-41 sequence ...
متن کاملThree-dimensional compartmentalization of myosin heavy chain and myosin light chain isoforms in dog thyroarytenoid muscle.
The thyroarytenoid muscle, a vocal fold adductor, has important roles in airway protection (e.g., prevention of aspiration) and phonation. Isoform expression of myosin heavy chain (MHC), a major determinant of muscle-shortening velocity, has been reported to be heterogeneous in this muscle in several mammals, differing markedly between the medial and lateral divisions. The objective was to dete...
متن کاملRegulation of human heart contractility by essential myosin light chain isoforms.
Most of the patients with congenital heart diseases express the atrial myosin light chain 1 (ALC-1) in the right ventricle. We investigated the functional consequences of ALC-1 expression on the myosin cycling kinetics in the intact sarcomeric structure using multicellular demembranated fibers ("skinned fibers") from the right ventricular infundibulum of patients with Tetralogy of Fallot (TOF),...
متن کاملModulation of contractility in human cardiac hypertrophy by myosin essential light chain isoforms.
Cardiac hypertrophy is an adaptive response that normalizes wall stress and compensates for increased workload. It is accompanied by distinct qualitative and quantitative changes in the expression of protein isoforms concerning contractility, intracellular Ca(2+)-homeostasis and metabolism. Changes in the myosin subunit isoform expression improves contractility by an increase in force generatio...
