(20) Together these results suggest that IVC may operate as a selective activator of calpain both in the cytosol and at the membrane level; in the latter case in synergism with the activation induced by association of the proteinase to the cell membrane.
Actuate
Definition:
(v. t.) To put into action or motion; to move or incite to action; to influence actively; to move as motives do; -- more commonly used of persons.
(v. t.) To carry out in practice; to perform.
(a.) Put in action; actuated.
Example Sentences:
(1) Active filling (-10 mmHg) inside inner blood sacs was produced by the suction effects of the outer sacs attached to a moving actuator.
