Answer:
It transmit mechanical force and signals.
Step-by-step explanation:
Focal adhesions are large macromolecular which is responsible for the transmission of mechanical force and regulatory signals between the extracellular matrix and an interacting cell. Focal adhesions act as the mechanical linkages to the ECM, and serves as a biochemical signaling hub to direct numerous signaling proteins at sites of integrin binding and clustering. 68-kD protein also known as paxillin is a type of protein which is part of cytoskeletal component that localizes to the focal adhesions.
