Adrb2 Gene Summary [Rat]
Enables several functions, including G-protein alpha-subunit binding activity; beta2-adrenergic receptor activity; and signaling receptor binding activity. Involved in several processes, including chemical synaptic transmission; diaphragm contraction; and positive regulation of monoatomic ion transport. Located in several cellular components, including caveola; neuronal cell body membrane; and sarcolemma. Is active in Schaffer collateral - CA1 synapse; glutamatergic synapse; and postsynaptic membrane. Used to study cardiomyopathy (multiple); congestive heart failure; kidney disease (multiple); and lung disease (multiple). Biomarker of several diseases, including acute kidney failure; artery disease (multiple); congestive heart failure; polycystic ovary syndrome; and ulcerative colitis. Human ortholog(s) of this gene implicated in several diseases, including autoimmune disease (multiple); disease of metabolism (multiple); kidney failure (multiple); lung disease (multiple); and open-angle glaucoma (multiple). Orthologous to human ADRB2 (adrenoceptor beta 2). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Adrb2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
