UniProt functional annotation for P08588

UniProt code: P08588.

Organism: Homo sapiens (Human).
Taxonomy: Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini; Catarrhini; Hominidae; Homo.
 
Function: Beta-adrenergic receptors mediate the catecholamine-induced activation of adenylate cyclase through the action of G proteins. This receptor binds epinephrine and norepinephrine with approximately equal affinity. Mediates Ras activation through G(s)-alpha- and cAMP-mediated signaling. Involved in the regulation of sleep/wake behaviors (PubMed:31473062). {ECO:0000269|PubMed:12391161, ECO:0000269|PubMed:31473062}.
 
Subunit: Interacts (via C-terminus PDZ motif) with RAPGEF2; the interaction is direct. Interacts with GOPC, MAGI3 and DLG4. {ECO:0000269|PubMed:12391161, ECO:0000269|PubMed:15358775}.
Subcellular location: Cell membrane {ECO:0000250|UniProtKB:P18090}; Multi-pass membrane protein {ECO:0000250|UniProtKB:P18090}. Early endosome. Note=Colocalizes with RAPGEF2 at the plasma membrane (By similarity). Localized at the plasma membrane. Found in the Golgi upon GOPC overexpression. {ECO:0000250}.
Domain: The PDZ domain-binding motif mediates competitive interactions with GOPC, MAGI3 and DLG4 and plays a role in subcellular location of the receptor.
Ptm: Homologous desensitization of the receptor is mediated by its phosphorylation by beta-adrenergic receptor kinase.
Polymorphism: Genetic variations in ADRB1 are associated with inter- individual variability in the resting heart rate. This quantitative trait has been significantly correlated with cardiovascular morbidity and mortality [MIM:607276]. {ECO:0000269|PubMed:11854867}.
Polymorphism: Genetic variations in ADRB1 are associated with the familial natural short sleep 2 (FNSS2) phenotype, an autosomal dominant trait [MIM:618591]. Individuals with this trait require less sleep in any 24-hour period than is typical for their age group. {ECO:0000269|PubMed:31473062}.
Similarity: Belongs to the G-protein coupled receptor 1 family. Adrenergic receptor subfamily. ADRB1 sub-subfamily. {ECO:0000255|PROSITE-ProRule:PRU00521}.
