actomyosin

 [ak″to-mi´o-sin]
the complex of actin and myosin constituting muscle fibers and responsible for the contraction and relaxation of muscle.
Actomyosin in muscle fibers. From Applegate, 2000.

ac·to·my·o·sin

(ak'tō-mī'ō-sin),
A protein complex composed of actin and myosin; it is the essential contractile substance of muscle fiber, active with MgATP.

actomyosin

(ăk′tə-mī′ə-sĭn)
n.
A complex of actin, myosin, and associated proteins that is responsible for contraction in cells, especially muscle cells.

Actomyosin

(1) A term which considers the molecular motors—actin and myosin—as a single functional unit
(2) A G actin-like contractile protein complex found in platelets which consists of actin and myosin in a actin:myosin ratio of 100:1—muscle has a ratio of 7:1—and which appears with platelet activation.

ac·to·my·o·sin

(ak'tō-mī'ō-sin)
A protein complex composed of actin and myosin; the essential contractile substance of muscle fiber.

actomyosin

a protein formed by the interaction of ACTIN and MYOSIN. It is closely concerned with the process of MUSCLE contraction.
