myosin

 [mi´o-sin]
one of the two main proteins of muscle. Myosin and actin are the proteins involved in contraction of muscle fibers.

my·o·sin

(mī'ō-sin),
A globular protein present in muscle and in nonmuscle cells that has an ATPase activity; in combination with actin, it forms actomyosin; myosin forms the thick filaments in muscle.

myosin

(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.

my·o·sin

(mī'ō-sin)
A globulin present in muscle; in combination with actin, it forms actomyosin; myosin forms the thick filaments in muscle.

myosin

a protein found in the thick filaments of the SARCOMERES OF MUSCLE. Myosin combines with ACTIN to produce ACTOMYOSIN during contraction.

my·o·sin

(mī'ō-sin)
A globulin present in muscle; in combination with actin, it forms actomyosin.
