		Gene Name		ADRB1
		Uniprot ID		ADRB1_HUMAN
		KEGG Pathway		hsa:153
		Protein Family		G-protein coupled receptor 1 family
		Protein 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). Click to Show/Hide
