MYH4 Products

Species: Hu


MYH4, also known as Myosin-4, is a 1939 amino acid protein that is 223 kDa, predominantly found in myocytes mediates plus-ended movement along microfilaments and involved in muscle contraction through cyclic interactions with actin-rich thin filaments, creating a contractile force. It is regulated by phosphorylation via myosin light chain kinase (MLCK) and by intracellular Ca2+ concentrations. Current research is being performed on several diseases and disorders including congestive heart failure, yaws, myocarditis, hermaphroditism, liver disease, pharyngitis, and alcoholism. This protein is involved in cell adhesion integrin-mediated cell adhesion and migration, cell adhesion tight junctions, cytoskeleton remodeling regulation of actin cytoskeleton by Rho GTPases, immune response CCR3 signaling in eosinophils, development MAG-dependent inhibition of neurite outgrowth, RhoA, antioxidant action of vitamin-C, transendothelial migration of leukocytes, actin nucleation by ARP-WASP complex, epithelial adherens junctions, inhibitory action of lipoxins on neutrophil migration, membrane trafficking, translocation of GLUT4 to the plasma membrane, translocation of GLUT4 vesicle and docking at the plasma membrane, and Viral myocarditis pathways forming interactions with ESR2, NTHL1, S100A4, USP15, C12orf44, CNBP, ACTB, and over 30 other proteins.
