SMART accession number:SM01241
Description: Integrins are a group of transmembrane proteins which function as extracellular matrix receptors and in cell adhesion. Integrins are ubiquitously expressed and are heterodimeric, each composed of an alpha and beta subunit. Several variations of the the alpha and beta subunits exist, and association of different alpha and beta subunits can have different a different binding specificity. This domain corresponds to the cytoplasmic domain of the beta subunit.
