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

Actin (red) interacts with myosin, shown in globular form (pink) and a filament form (black line). The model shown is that of H. E. Huxley, modified to indicate bending (curved arrow) near the ...

Our skin and mucous membranes are protected by epithelial cells. This 'barrier' tissue performs its function thanks to specialized structures called 'junctions'. They ensure cell cohesion and regulate ...

Furthermore, cofilin, which promotes actin turnover, and myosin, which interacts with actin ... the vesicle fusion process ...
