myosin defined in 1951 yearmyosin - myosin;
myosin - Protein that in conjunction with actin provides the structural framework of the contractile mechanism in muscle and probably in other cells. A myosin molecule has an attachment site for actin, and an enzymic site that breaks down ATP with liberation of energy for contraction. The generally accepted sliding filament hypothesis ascribes contraction to myosin molecules sliding along actin filaments.
