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 ...

Actin is a long fiber, and myosin like a tiny motor that moves ... Cho et al, Actomyosin contraction in the follicular ...

When a person dies and their ATP is depleted, actin and myosin cannot be broken down, leading to the permanent contraction of the muscles and stiffening of the body. Nurse Julie said: 'I have seen ...

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 ...
