Question

Quizplus · Accepted Answer

Integrins are transmembrane proteins that span the plasma membrane and link the extracellular matrix to the cell's cytoskeleton, providing mechanical support and signaling cues for cellular processes such as migration, adhesion, and differentiation. They do not create a filamentous meshwork, act as membrane-bounded enzymes, or serve as cell recognition molecules (although they can bind to specific ligands for signaling purposes).
