Function
Integrin alpha-2/beta-1 is a receptor for laminin, collagen, collagen C-propeptides, fibronectin and E-cadherin. It recognizes the proline-hydroxylated sequence G-F-P-G-E-R in collagen. It is responsible for adhesion of platelets and other cells to collagens, modulation of collagen and collagenase gene expression, force generation and organization of newly synthesized extracellular matrix.
Heterodimer of an alpha and a beta subunit. Alpha-2 associates with beta-1. Interacts with HPS5 and RAB21. Binds to human echoviruses 1 and 8 capsid proteins and acts as a receptor for these viruses. Interacts (via ITAG2 I-domain) with rotavirus A VP4; this interaction only occurs in rotavirus integrin-dependent strains, for which ITGA2 acts as a receptor.
