IL2RG / CD132 Protein Description
The interleukin 2 receptor (IL-2R) is a heterotrimeric protein expressed on the surface of certain immune cells, such as lymphocytes, which binds and responds to the cytokine IL-2. Three distinct chains of IL-2R, termed as α, β and γ, which are non-covalently associated are identified. The α and β chains are involved in binding IL-2, while signal transduction following cytokine interaction is carried out by the γ chain, along with the β subunit which are members of the type I cytokine receptor family. The α chain of the IL-2R can bind to the β chain before receptor interaction with IL-2. The γ chain alone has a very weak affinity for IL-2, but after the ligand is bound to the α/β heterodimer, the γ chain becomes recruited to the complex to form a very stable macromolecular quaternary ligand/receptor complex. It is proposed that the γ chain is common to the IL2, IL4, IL7, IL21 and probably also the IL13 receptors.
