The sliding filament theory describes the mechanism that allows muscles to contract. According to this theory, myosin (a motor protein) binds to actin. The myosin then alters its configuration, resulting in a "stroke" that pulls on the actin filament and causes it to slide across the myosin filament.]]> 2021-10-19 19:18:37 UTC https://padlet.com/k1522153/iu899hm0pejg1osr/wish/1828277362 k1522153 https://padlet.com/k1522153/iu899hm0pejg1osr/wish/1828281134 A protein that forms (together with myosin) the contractile filaments of muscle cells, and is also involved in motion in other types of cell.
