Human IL-2 R gamma / CD132 Protein, His Tag (MALS verified)
分子別名(Synonym)
IL2RG,CD132,CIDX,IMD4,P64,SCIDX,SCIDX1,gammaC
表達區(qū)間及表達系統(tǒng)(Source)
Human IL-2 R gamma, His Tag (ILA-H52H5) is expressed from human 293 cells (HEK293). It contains AA Leu 23 - Asn 254 (Accession # P31785-1).
Predicted N-terminus: Leu 23
蛋白結(jié)構(gòu)(Molecular Characterization)
This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 29.3 kDa. The protein migrates as 55-65 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
內(nèi)毒素(Endotoxin)
Less than 1.0 EU per μg by the LAL method.
純度(Purity)
>95% as determined by SDS-PAGE.
制劑(Formulation)
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

背景(Background)
IL-2R是一種異三聚體蛋白,與細胞因子IL-2結(jié)合并產(chǎn)生反應。鑒定出三條不同的IL-2R鏈,稱為α、β和γ,它們是非共價結(jié)合的。α鏈和β鏈參與結(jié)合IL-2,而細胞因子相互作用后的信號轉(zhuǎn)導由γ鏈和β亞基進行。IL-2R的α鏈可以在受體與IL-2相互作用之前與β鏈結(jié)合。單獨的γ鏈對IL-2的親和力非常弱,但在配體與α/β異二聚體結(jié)合后,γ鏈被招募到復合物中,形成非常穩(wěn)定的大分子四元配體/受體復合物。
白細胞介素-2受體亞基γ(IL2RG),也稱為細胞因子受體共同亞基γ,CD抗原CD132,gammaC,p64,屬于I型細胞因子受體家族或5型亞家族。IL2RG位于骨髓中未成熟造血細胞的表面。IL2RG缺陷是嚴重聯(lián)合免疫缺陷X連鎖T細胞陰性/B細胞陽性/NK細胞陰性(XSCID)的原因。
