IL-2 receptor
The interleukin-2 receptor (IL-2R) is a heterotrimeric protein expressed on the surface of certain immune cells, such as lymphocytes, that binds and responds to a cytokine called IL-2. == Composition ==
IL-2 binds to the IL-2 receptor, which has three forms, generated by different combinations of three different proteins, often referred to as "chains": α (alpha) (also called IL-2Rα, CD25, or Tac antigen), β (beta) (also called IL-2Rβ, or CD122), and γ (gamma) (also called IL-2Rγ, γc, common gamma chain, or CD132); these subunits are also parts of receptors for other cytokines.〔Warren J.

Philadelphia : Wolters Kluwer/Lippincott Williams & Wilkins, c2008. ISBN 9780781765190〕 The β and γ chains of the IL-2R are members of the type I cytokine receptor family.
