Muscle - Actin-Myosin, Regulation, Contraction: Mixtures of myosin and actin in test tubes are used to study the relationship between the ATP breakdown reaction and the interaction of myosin and actin. The ATPase reaction can be followed by measuring the
Upon phosphorylation of Serine 19 of the RLC of SMM by myosin light chain kinase (MLCK), SMM filaments and actin (thin) filaments slide over one another and the cell contracts. The effect of the filamentous conformation of SMM on the kinetics underlying the interactions with MLCK and actin ...

Cardiac muscle contraction is driven by cyclic interactions between myosin S1 heads of thick filaments and actin-containing thin filaments. It is regulated by troponin–tropomyosin (Tn–Tpm) complexes that, at rest, occlude myosin binding sites along filamentous actin (F-actin) and limit S1-thin ...
Heavy meromyosin (HMM) labeling was used to identify the nature of the filaments which form bundles in the cytoplasm of the pericytes in brain tissue. Rat brain tissue pieces were incubated in glycerol solutions at 4 degrees and then transferred into buffer (pH 7.0), (1) without HMM, (2)...
The contractility of platelets has been attributed to an actomyosin-like protein which has been well defined on a physicochemical basis. Moreover, platelets contain ±80 A filaments which resemble actin filaments in smooth muscle. Studies were undertaken on human and bovine platelets to better define...
actin and myosin are activated. Myosin works as a motor, hydrolyzingadenosine triphosphate(ATP) to release energy in such a way that a myosin filament moves along an actin filament, causing the two filaments to slide past each other. The thin actin filaments and the thick myosin filaments are...
MUSCLE contraction occurs by mutual sliding between thick (myosin) and thin (actin) filaments 1,2 . But the physical and chemical properties of the sliding force are not clear; even the precise direction of sliding force generated at each cross-bridge is not known. We report here the use of...
Cardiac sarcomeres are composed of overlapping actin-thin filaments and myosin-thick filaments. Efficient muscle contraction is dependent on the proper overlap of thick and thin filaments; therefore filament lengths are tightly regulated. The actin-thin
