Gene: ADRA2A (adrenoceptor alpha 2A) Homo sapiens
Symbol: ADRA2A
Name: adrenoceptor alpha 2A
Description: Exhibits several functions, including catecholamine binding activity; enzyme binding activity; and protein dimerization activity. Involved in several processes, including adrenergic receptor signaling pathway; negative regulation of insulin secretion involved in cellular response to glucose stimulus; and positive regulation of cellular protein metabolic process. Localizes to cytoplasm; integral component of plasma membrane; and receptor complex. Implicated in attention deficit hyperactivity disorder and type 2 diabetes mellitus.
Type: protein-coding
RefSeq Status: REVIEWED
Also known as: ADRA2; ADRA2R; ADRAR; adrenergic receptor, alpha 2a; adrenergic, alpha-2A-, receptor; alpha-2 adrenergic receptor subtype C10; alpha-2-adrenergic receptor, platelet type; alpha-2A adrenergic receptor; alpha-2A adrenoceptor; alpha-2A adrenoreceptor; alpha-2AAR subtype C10; ALPHA2AAR; ZNF32
