which type of cytoskeletal protein is also involved in muscle contractions?
actin
vinculin









































in mammalian cells, vinculin is a membrane-cytoskeletal protein in focal adhesion plaques that is involved in linkage of integrin adhesion molecules to the actin cytoskeleton. vinculin is a cytoskeletal protein associated with cell-cell and cell-matrix junctions, where it is thought to function as one of several interacting proteins involved in anchoring f-actin to the membrane.









































discovered independently by benny geiger and keith burridge, its sequence is 20%-30% similar to α-catenin, which serves a similar function.

in 1856 guillaume duchenne announced that alternating was superior to direct current for electrotherapeutic triggering of muscle contractions. what he called the 'warming effect' of direct currents irritated the skin, since, at voltage strengths needed for muscle contractions, they cause the skin to blister (at the anode) and pit (at the cathode). furthermore, with dc each contraction required the current to be stopped and restarted. moreover, alternating current could produce strong muscle contractions regardless of the condition of the muscle, whereas dc-induced contractions were strong if the muscle was strong, and weak if the muscle was weak.
