IL-2R gamma/CD132 Protein, Human (HEK293, His-Avi)

IL-2R gamma (CD132), a type I cytokine receptor expressed on leucocyte subsets, is a receptor for IL-2. IL-2R gamma forms heterodimer with IL-2R beta, and increases the affinity of IL-2R beta for IL-2^[1]. IL-2R gamma plays an important role in the development, activation, proliferation, differentiation and regulation of lymphocytes and other cell types^[2]. IL-2R gamma/CD132 Protein, Human (HEK293, His-Avi) is a recombinant human extracellular region of IL-2R gamma (L23-N254) with a C-Terminal Avi and a His tag, which is produced in HEK293 cells.

IL-2R gamma (CD132), a receptor for IL-2, is a member of the type I cytokine receptor family and type 5 subfamily. IL-2R gamma is expressed in leucocyte subsets and human monocytes^[1][3]. Human IL-2R gamma consists of extracellular domain (L23-A262), helical domain (V263-L283), and cytoplasmic domain (E284-T369).
The sequence of amino acids in IL-2R beta differs in different species. Human IL-2R gamma shares <75% aa sequence identity with mouse and rats.
IL-2R gamma has low-affinity for IL-2, but has intermediate affinity for IL-2 when forming heterodimer with IL-2R beta. IL-2R beta/gama heterodimer complex transduces a signal when IL-2 concentrations are relatively high^[1]. IL-2R gamma can be utilized by the IL-2, IL-4, IL-7, IL-9, and IL-15 receptor, and takes part in the development, activation, proliferation, differentiation and regulation of lymphocytes and other cell types^[2]. IL-2R gamma is tightly up-regulated by IL-2 and IFN gamma^[3]. Mutations of L-2R gamm cause human X-linked severe combined immunodeficiency (XSCID)^[4].
IL-2R gamma is involved in inflammatory response, and mediates activation of the cells^[1].

IL-2R gamma (human) migrates with a molecular weight corresponding to 55–60 kDa (immunoblotting of lysates prepared from Sf9 cells infected with VL1392-hIL-2Rγ)^[5].
IL-2R gamma binds to IL-2 in recombinant IL-2R gamma plasmid (pGEX-4T-1-IL-2Rγ)-transfected 293T cells^[6].
