Summary: Enables alpha2-adrenergic receptor activity. Involved in several processes, including negative regulation of secretion by cell; negative regulation of uterine smooth muscle contraction; and response to morphine. 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 alcohol dependence; hypertension; morphine dependence; and type 2 diabetes mellitus. Human ortholog(s) of this gene implicated in several diseases, including alcohol dependence; attention deficit hyperactivity disorder; familial partial lipodystrophy; nicotine dependence; and type 2 diabetes mellitus. Orthologous to human ADRA2A (adrenoceptor alpha 2A). [provided by Alliance of Genome Resources, Dec 2024]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
