ADRB2

This gene encodes beta-2-adrenergic receptor which is a member of the G protein-coupled receptor superfamily. This receptor is directly associated with one of its ultimate effectors, the class C L-type calcium channel Ca(V)1.2. This receptor-channel complex also contains a G protein, an adenylyl cyclase, cAMP-dependent kinase, and the counterbalancing phosphatase, PP2A. The assembly of the signaling complex provides a mechanism that ensures specific and rapid signaling by this G protein-coupled receptor. This gene is intronless. Different polymorphic forms, point mutations, and/or downregulation of this gene are associated with nocturnal asthma, obesity and type 2 diabetes.

Interaction

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).
