The alpha-2B adrenergic receptor (α_2B adrenoreceptor), also known as ADRA2B, is an alpha-2 adrenergic receptor, and also denotes the human gene encoding it.^[1]

Receptor

Alpha-2-adrenergic receptors include 3 highly homologous subtypes: alpha_2A, alpha_2B, and alpha_2C. These receptors have a critical role in regulating neurotransmitter release from sympathetic nerves and from adrenergic neurons in the central nervous system.

Gene

This gene encodes the alpha_2B subtype, which was observed to associate with eIF-2B, a guanine nucleotide exchange protein that functions in regulation of translation. A polymorphic variant of the alpha_2B subtype, which lacks 3 glutamic acids from a glutamic acid repeat element, was identified to have decreased G protein-coupled receptor kinase-mediated phosphorylation and desensitization; this polymorphic form is also associated with reduced basal metabolic rate in obese subjects and may therefore contribute to the pathogenesis of obesity. This gene contains no introns in either its coding or untranslated sequences.^[1]
