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.

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.

actomyosin

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

actomyosin

system of actin filaments and myosin particles forming muscle fibres that interact causing muscle contraction (see muscle contraction)
