Question

Quizplus · Accepted Answer

Integrins are transmembrane proteins that function as receptors for extracellular matrix (ECM) proteins, such as collagen and fibronectin, as well as cell adhesion molecules (CAMs). They are capable of transmitting signals from the ECM to the internal cytoskeleton and the nucleus, thereby influencing cell behaviour such as proliferation, differentiation, and apoptosis. Gap junctions, plasmodesmata, DNA and RNA, and the nucleus do not directly mediate communication between the ECM and the cell interior.
