CC -!- FUNCTION: Beta-adrenergic receptors mediate the catecholamine-induced
CC activation of adenylate cyclase through the action of G proteins. The
CC beta-2-adrenergic receptor binds epinephrine with an approximately 30-
CC fold greater affinity than it does norepinephrine (By similarity).
CC {ECO:0000250|UniProtKB:P07550}.
CC -!- SUBUNIT: Binds SLC9A3R1 and GPRASP1. Interacts with ARRB1 and ARRB2.
CC Interacts with SRC (By similarity). Interacts with USP20 and USP33 (By
CC similarity). Interacts with VHL; the interaction, which is increased on
CC hydroxylation of ADRB2, ubiquitinates ADRB2 leading to its degradation.
CC Interacts with EGLN3; the interaction hydroxylates ADRB2 facilitating
CC VHL-E3 ligase-mediated ubiquitination. Interacts (via PDZ-binding
CC motif) with SNX27 (via PDZ domain); the interaction is required when
CC endocytosed to prevent degradation in lysosomes and promote recycling
CC to the plasma membrane. Interacts with CNIH4. Interacts with ARRDC3.
CC Interacts with NEDD4 (By similarity). Interacts with MARCHF2 (By
CC similarity). {ECO:0000250|UniProtKB:P07550}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250|UniProtKB:P07550};
CC Multi-pass membrane protein {ECO:0000250|UniProtKB:P07550}. Early
CC endosome {ECO:0000250|UniProtKB:P07550}. Golgi apparatus
CC {ECO:0000250|UniProtKB:P07550}. Note=Colocalizes with VHL at the cell
CC membrane. Activated receptors are internalized into endosomes prior to
CC their degradation in lysosomes. Activated receptors are also detected
CC within the Golgi apparatus. {ECO:0000250|UniProtKB:P07550}.
CC -!- PTM: Palmitoylated; may reduce accessibility of Ser-345 and Ser-346 by
CC anchoring Cys-341 to the plasma membrane. Agonist stimulation promotes
CC depalmitoylation and further allows Ser-345 and Ser-346 phosphorylation
CC (By similarity). {ECO:0000250}.
CC -!- PTM: Phosphorylated by PKA and BARK upon agonist stimulation, which
CC mediates homologous desensitization of the receptor. PKA-mediated
CC phosphorylation seems to facilitate phosphorylation by BARK.
CC -!- PTM: Phosphorylation of Tyr-141 is induced by insulin and leads to
CC supersensitization of the receptor. {ECO:0000250}.
CC -!- PTM: Polyubiquitinated. Agonist-induced ubiquitination leads to sort
CC internalized receptors to the lysosomes for degradation.
CC Deubiquitination by USP20 and USP33, leads to ADRB2 recycling and
CC resensitization after prolonged agonist stimulation. USP20 and USP33
CC are constitutively associated and are dissociated immediately after
CC agonist stimulation. Ubiquitination by the VHL-E3 ligase complex is
CC oxygen-dependent (By similarity). {ECO:0000250}.
CC -!- PTM: Hydroxylation by EGLN3 occurs only under normoxia and increases
CC the interaction with VHL and the subsequent ubiquitination and
CC degradation of ADRB2. {ECO:0000250}.
CC -!- PTM: Palmitoylated. Mainly palmitoylated at Cys-341. Palmitoylation may
CC reduce accessibility of phosphorylation sites by anchoring the receptor
CC to the plasma membrane. Agonist stimulation promotes depalmitoylation
CC and further allows Ser-345 and Ser-346 phosphorylation. Also undergoes
CC transient, ligand-induced palmitoylation at Cys-265 probably by ZDHHC9,
CC ZDHHC14 and ZDHHC18 within the Golgi. Palmitoylation at Cys-265
CC requires phosphorylation by PKA and receptor internalization and
CC stabilizes the receptor. Could be depalmitoylated by LYPLA1 at the
CC plasma membrane. {ECO:0000250|UniProtKB:P07550}.
CC -!- SIMILARITY: Belongs to the G-protein coupled receptor 1 family.
CC Adrenergic receptor subfamily. ADRB2 sub-subfamily.
CC {ECO:0000255|PROSITE-ProRule:PRU00521}.
