Gene: Adra2a (adrenoceptor alpha 2A) Rattus norvegicus
Symbol: Adra2a
Name: adrenoceptor alpha 2A
RGD ID: 2056
Description: Enables alpha2-adrenergic receptor activity. Involved in several processes, including negative regulation of secretion by cell; negative regulation of uterine smooth muscle contraction; and thermoception. Located in axon terminus and neuronal cell body. Is active in GABA-ergic synapse; glutamatergic synapse; and synaptic membrane. Used to study anxiety disorder and depressive disorder. Biomarker of hypertension and type 2 diabetes mellitus. Human ortholog(s) of this gene implicated in attention deficit hyperactivity disorder and type 2 diabetes mellitus. Orthologous to human ADRA2A (adrenoceptor alpha 2A); INTERACTS WITH (R)-adrenaline; (R)-noradrenaline; 2,3,4,7,8-Pentachlorodibenzofuran.
