The<unk>  (CD123) is a molecule found on cells which helps transmit the signal of<unk> -3, a soluble cytokine important in the immune system. The gene coding for the receptor is located in the pseudoautosomal region of the X and Y chromosomes. The receptor belongs to the type I cytokine receptor family and is a heterodimer with a unique alpha chain paired with the common beta (beta c or CD131) subunit. The gene for the alpha subunit is 40 kilobases long and has 12 exons.
