分子别名(Synonym)
IL2RG,CD132,CIDX,IMD4,P64,SCIDX,SCIDX1,gammaC
表达区间及表达系统(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
蛋白结构(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.
内毒素(Endotoxin)
Less than 1.0 EU per μg by the LAL method / rFC method.
纯度(Purity)
>95% as determined by SDS-PAGE.
制剂(Formulation)
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

背景介绍
白细胞介素2受体(IL-2R)是一种异源三聚体蛋白,可结合并响应细胞因子IL-2。该受体由α、β和γ三条非共价结合的多肽链构成。其中α链与β链参与IL-2的结合,而细胞因子结合后的信号转导则由γ链与β亚基共同完成。在与IL-2结合前,IL-2R的α链即可与β链发生结合。γ链单独对IL-2的亲和力极弱,但当配体与α/β异二聚体结合后,γ链会被招募至复合体中,形成高度稳定的大分子四级配体/受体复合物。
白细胞介素2受体γ亚基(IL2RG)又称细胞因子受体共同γ链、CD抗原CD132、gammaC、p64,属于I型细胞因子受体家族中的第5亚族。该蛋白表达于骨髓未成熟造血细胞表面,其基因缺陷会导致X连锁严重联合免疫缺陷症(表现为T细胞缺乏、B细胞正常、NK细胞缺乏的XSCID)。
