NettetMany integrins bind to their ligands through the Arg-Gly-Asp tripeptide sequence, which is displayed by a number of extracellular matrix proteins, plasma proteins, and even viruses. Unlike many other classes of receptors, the integrins participate in bidirectional signaling across the membrane.

Integrins have two main functions, attachment of the cells to the ECM and signal transduction from the ECM to the cells. They are also involved in a wide range of other biological activities, including extravasation, cell-to-cell adhesion, cell migration, and as receptors for certain viruses, such as adenovirus, echovirus, hantavirus, and foot-and-mouth disease, polio virus and other viruses.
