Integrins as cell surface receptors
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. Nettet30. mar. 2024 · Such attachments between cells and ECM are mainly controlled by integrins. Their clustering involves many other proteins (vinculin, talin, paxilin) [1]. Integrins are heterodimeric alpha/beta cell-surface adhesion receptors, signalling across the membrane in both directions.
