Alpha-2-adrenergic receptor (ADRA2), also known as platelet type adrenoceptor alpha-2A ,is a member of G protein-coupled receptor superfamily. This gene, which can identify a DraI RFLP of the ADRAR gene, mapped to 10q23-q25, is found in the distal region of mouse chromosome 19 and abundantly expressed in giant cell. ADRA2 acts a critical role in regulating neurotransmitter release from sympathetic nerves and from adrenergic neurons in the central nervous system. It has 3 highly
homologous subtypes: ADRA2A; ADRA2B and ADRA2C. Studies in mouse suggested that both the ADRA2A and ADRA2C subtypes are required for normal presynaptic control of transmitter release from sympathetic nerves in the heart and from central noradrenergic neurons. ADRA2A receptors inhibited transmitter release at high stimulation frequencies, whereas the ADRA2C subtype modulated neurotransmission at lower levels of nerve activity.
