Which mechanism best describes the process by which focal adhesions are formed to promote cell motility?

Question

Quizplus · Accepted Answer

Focal adhesions are formed when transmembrane receptors, such as integrins, bind to extracellular matrix proteins, such as fibronectin. This binding triggers a signaling cascade that results in the recruitment of intracellular proteins, including talin and vinculin, to the site of the adhesion. These proteins then link the transmembrane receptor to the actin cytoskeleton to promote cell motility.
