ADRA2B(redirected from Alpha-2B adrenoceptor)
ADRA2BA gene on chromosome 2p13-q13 that encodes alpha-2B-adrenergic receptor, a member of the G protein-coupled receptor superfamily, which plays a critical role in regulating neurotransmitter release from sympathetic nerves and from adrenergic neurons in the CNS, smooth muscle contraction and thermoregulation. The alpha2B subtype associates with EIF-2B, a guanine nucleotide exchange protein that regulates translation.
