NettetThe initial production of α and β chains takes place in the cellular cytoplasm, both of these chains being necessary for complete β2 family differentiation, the β2 family acting as cell adhesion molecules. β2 and β7 integrins have been identified only in leukocytes, their cell surface co-receptors being members of the Ig gene superfamily. NettetIntegrins are specialized cell surface receptors that interact primarily with ECM proteins such as fibronectin, collagen, and laminin. Some specialized integrins interact with cell surface receptors on other cells. Integrins are heterodimers composed of …
