my·o·sin

 (mī′ə-sĭn)
n.
Any of a class of proteins that bind with actin filaments and generate many kinds of cell movement, especially the contraction of myofibrils in muscle cells.

[Greek muos, genitive of mūs, muscle; see myo- + -in.]

myosin

(ˈmaɪəsɪn)
n
(Biochemistry) the chief protein of muscle that interacts with actin to form actomyosin during muscle contraction; it is also present in many other cell types
