MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This intronless gene encodes a seven-pass transmembrane protein. This protein is a member of a subfamily of G protein-coupled receptors that regulate neurotransmitter release from sympathetic nerves and from adrenergic neurons in the central nervous system. [provided by RefSeq, Apr 2014]
PHENOTYPE: Homozygous null mice exhibit poor survival and breeding, lack the vasoconstrictor response to alpha2-adrenergic receptor agonists, and display background strain dependent postnatal respiratory failure. Heterozygotes show an attenuated hypertensive response to subtotal nephrectomy and salt loading. [provided by MGI curators]
