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 ...

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 ...

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 ...

I. Rayment, H.M. Holden, M. Whittaker, C.B. Yohn, M. Lorenz. K.C. Holmes, R.A. Milligan, "Structure of the actin-myosin complex and its implications for muscle ...

Muscle contraction occurs when these myofilaments ... smooth muscle cells shorten via the movement of actin and myosin myofilaments. Examples of involuntary smooth muscles include: The one ...

In this type of contraction, a protein in your muscles called myosin binds to another protein called actin and drags it to shorten muscle fibres. Now imagine you start at the top: your muscles are ...

The actin cytoskeleton plays a central role in multiple biological processes including muscle contraction, cell motility, cell division, endocytosis, and phagocytosis. The group is part of Finnish ...
