arrestin beta 1
ARRB1 encodes arrestin beta 1, the human beta-arrestin-1 protein. Beta-arrestin-1 is a cytosolic regulator of agonist-activated G protein-coupled receptors (GPCRs), coordinating receptor desensitization, internalization and subsequent trafficking. Abmium catalogue products linked below support research into ARRB1 expression and GPCR regulatory biology.

Research context & evidence
Target information is kept separate from product-level validation so you can review the biology and the reagent evidence independently.
Beta-arrestin-1 binds activated, phosphorylated GPCRs and limits further coupling to cognate G proteins, contributing to homologous receptor desensitization. It also functions as an endocytic adaptor, recruiting components including AP-2 and clathrin-associated machinery to promote receptor internalization. These activities place ARRB1 at an important control point between receptor activation, trafficking and resensitization.
ARRB1 is studied in GPCR signalling, receptor trafficking, signal desensitization and immune or neuronal receptor regulation. Experimental interpretation should distinguish ARRB1 abundance from receptor-specific recruitment or signalling state.
