DESCRIPTION

Also known as ADRB2_HUMAN, ADRB2, ADRB2R, B2AR. Beta-adrenergic receptors mediate the catecholamine-induced activation of adenylate cyclase through the action of G proteins. The beta-2-adrenergic receptor binds epinephrine with an approximately 30-fold greater affinity than it does norepinephrine. Binds SLC9A3R1 and GPRASP1. Interacts with ARRB1 and ARRB2. Interacts with SRC (PubMed:9924018). Interacts with USP20 and USP33 (PubMed:19424180, PubMed:23166351). Interacts with VHL; the interaction, which is increased on hydroxylation of ADRB2, ubiquitinates ADRB2 leading to its degradation. Interacts with EGLN3; the interaction hydroxylates ADRB2 facilitating VHL-E3 ligase-mediated ubiquitination. Interacts (via PDZ-binding motif) with SNX27 (via PDZ domain); the interaction is required when endocytosed to prevent degradation in lysosomes and promote recycling to the plasma membrane. Interacts with CNIH4 (PubMed:24405750). Interacts with ARRDC3 (PubMed:20559325, PubMed:25220262). Interacts with NEDD4 (PubMed:23166351). Interacts with MARCHF2 (PubMed:23166351).
