E) none of these answers.

Question

Quizplus · Accepted Answer

Integrins are transmembrane proteins that span the cell membrane, providing a mechanical link between the extracellular matrix and the cell's cytoskeleton. They play a key role in cell adhesion, migration, and signaling. They do not create a filamentous meshwork in the inner surface of the membrane, act as enzymes, or are used for cell recognition purposes.
