Isolated integrin beta3 subunit cytoplasmic domains require membrane anchorage and the NPXY motif to recruit to adhesion complexes but do not discriminate between beta1- and beta3-positive complexes.

Abstract excerpt

Integrin adhesion receptors consist of non-covalently linked alpha and beta subunits each of which contains a large extracellular domain, a single transmembrane domain and a short cytoplasmic tail. Engaged integrins recruit to focal structures globally termed adhesion complexes. The cytoplasmic domain of the beta subunit is essential for this clustering. beta1 and beta3 integrins can recruit at distinct cellular...
