ARRB2 (Beta-arrestin-2) is a gene. In the public catalogues the evidence so far is association rather than a proven role.
Functions in regulating agonist-mediated G protein-coupled receptor (GPCR) signalling by mediating both receptor desensitisation and resensitisation processes. During homologous desensitisation, beta-arrestins bind to the GPCR-phosphorylated receptor and sterically preclude its coupling to the cognate G protein; the binding appears to require additional receptor determinants exposed only in the active receptor conformation. The beta-arrestins target many receptors for internalisation by acting as endocytic adapters (CLASPs, clathrin-associated sorting proteins) and recruiting the GPRCs to the adapter protein 2 complex 2 (AP-2) in clathrin-coated pits (CCPs).
Open Targets scores its association with cancer at 0.62 (direct and indirect evidence; datatypes literature 0.94, affected pathway 0.97, genetic association 0.00).

Functions in regulating agonist-mediated G protein-coupled receptor (GPCR) signalling by mediating both receptor desensitisation and resensitisation processes. During homologous desensitisation, beta-arrestins bind to the GPCR-phosphorylated receptor and sterically preclude its coupling to the cognate G protein; the binding appears to require additional receptor determinants exposed only in the active receptor conformation. The beta-arrestins target many receptors for internalisation by acting as endocytic adapters (CLASPs, clathrin-associated sorting proteins) and recruiting the GPRCs to the adapter protein 2 complex 2 (AP-2) in clathrin-coated pits (CCPs). However, the extent of beta-arrestin involvement appears to vary significantly depending on the receptor, agonist and cell type. Internalised arrestin-receptor complexes traffic to intracellular endosomes, where they remain uncoupled from G proteins. Two different modes of arrestin-mediated internalisation occur.
