Phosphorylation of the regulatory light chain subunit of smooth muscle myosin is sufficient, but not necessary for muscle… Expand Calponin (CaP), a thin filament-associated protein, plays an important role in the regulation of smooth muscle contractility. It… Expand Regulatory light chain (RLC) phosphorylation controls smooth muscle myosin's ability to act as a molecular motor. If thick… Expand The nature of the mechanism limiting the velocity of ATP-induced unidirectional movements of actin-myosin filaments in vitro is… Expand Embryonic chick heart ventricle myocytes retain the ability to alternate between proliferation and functional differentiation. A… Expand Four types of monoclonal antibody (BM-1, BM-2, BM-3 and BM-4) each having distinctive tissue specificity were obtained by… Expand We have sequenced a cDNA that encodes the nonmuscle myosin heavy chain from Drosophila melanogaster. An alternatively spliced… Expand Myosins purified from cardiac (porcine heart) and smooth (chicken gizzard) muscles were modified with 2,4,6… Expand Abstract Heavy meromyosin subfragment-1 from human platelets and chicken gizzard exhibited an identical chromatographic pattern… Expand Abstract 1. 1. Myosin light chains from skeletal and smooth muscles of the cow are compared using an analytical and a preparative… Expand
