Mgi Type | protein coding gene |
description | FUNCTION: Automated description from the Alliance of Genome Resources (Release 8.0.0) Enables alpha2-adrenergic receptor activity. Involved in negative regulation of insulin secretion and presynaptic modulation of chemical synaptic transmission. Acts upstream of or within G protein-coupled receptor signaling pathway and fear response. Is active in dopaminergic synapse. Is expressed in several structures, including central nervous system; genitourinary system; gut; limb segment; and sensory organ. 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). PHENOTYPE: Mice homozygous for targeted mutations that inactivate the gene fail to produce hypotensive responsiveness to alpha2AR agonists, including failure to inhibit voltage-gated Ca2+ currents and spontaneous neuronal firing.
