It has something to do with a sliding interaction between actin and myosin. In 1954, scientists published two groundbreaking papers describing the molecular basis of muscle contraction.

The conformation of myosin V when strongly bound to actin has been revealed by electron ... for the swinging cross-bridge model of muscle contraction proposed in 1969. Although muscle researchers ...

as actin building blocks are either added to or removed from the ends of filaments. According to the classical model, the generation of cell movement also requires the molecular motor myosin.

Our lab’s investigations of cardiac muscle contraction focus on the effects of cardiomyopathy-causing amino acid substitutions on myosin’s mechanical and ... We are also investigating actin filament ...

The actin filament exists as a structure of the fixed length and bears the muscle contraction and the adjustment on a muscular inside. The circulation and the molecule movements of the polymerization ...

Muscle contraction occurs when these myofilaments ... smooth muscle cells shorten via the movement of actin and myosin myofilaments. The one exception of an involuntary muscle is the myocardium ...

Thin, flexible protein strands called actin filaments act like bones for our cells and are critical for its movement. Supercomputer simulations have helped solve a decades-old mystery of how actin ...

b) It relies on the contraction of smooth muscles. c) It explains the movement of bones in the skeletal system. d) It describes the interaction between actin and myosin filaments. 9. Which of the ...
