Alpha2-C4, or Adrenoceptor alpha 2C, is a human gene encoded by ADRA2C. It may also be known as: Alpha-2C adrenergic receptor; Alpha-2 adrenergic receptor subtype C4; Alpha-2C adrenoreceptor; Alpha-2C adrenoceptor; Alpha-2CAR; ADRA2L2; ADRA2RL2; ADRARL2; ALPHA2CAR. The encoded protein has an amino acid length of 462 and a mass of 49.5 kDa. Alpha2-C4 is a member of the G-protein coupled receptor 1 family, Adrenergic receptor subfamily, ADRA2C sub-subfamily. Homologs of this gene exist in other organisms, including: Rat, Zebrafish, Frog, Chicken.
