The<unk>  <unk>  (or CD132), also known as interleukin-2 receptor subunit<unk> or IL-2RG, is a cytokine receptor sub-unit that is<unk>  to the receptor complexes for at least six different interleukin receptors: IL-2, IL-4, IL-7, IL-9, IL-15 and interleukin-21 receptor. The<unk>  glycoprotein is a member of the type I cytokine receptor family expressed on most lymphocyte (white blood cell) populations, and its gene is found on the X-chromosome of<unk> ls. This protein is located on the surface of immature blood-forming cells in bone marrow. One end of the protein resides outside the cell where it binds to cytokines and the other end of the protein resides in the interior of the cell where it transmits signals to the cell's nucleus. The<unk>  partners with other proteins to direct blood-forming cells to form lymphocytes (a type of white blood cell). The receptor also directs the growth and maturation of lymphocyte subtypes: T cells, B cells, and natural killer cells. These cells kill viruses, make antibodies, and help regulate the entire immune system.
