Summary: Enables alpha2-adrenergic receptor activity. Involved in several processes, including female pregnancy; positive regulation of MAPK cascade; and regulation of smooth muscle contraction. Predicted to be located in cell surface; cytosol; and intracellular membrane-bounded organelle. Predicted to be active in plasma membrane. Used to study hypertension. Human ortholog(s) of this gene implicated in diabetic neuropathy; hypertension; myocardial infarction; obesity; and type 2 diabetes mellitus. Orthologous to human ADRA2B (adrenoceptor alpha 2B).

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.
