分子別名(Synonym)
IL4R,CD124,IL4RA
表達區(qū)間及表達系統(tǒng)(Source)
Mouse IL-4 R alpha, His Tag (ILR-M52H1) is expressed from human 293 cells (HEK293). It contains AA Ile 26 - Arg 233 (Accession # NP_001008700).
Predicted N-terminus: Ile 26
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 26.3 kDa. The protein migrates as 37-45 kDa 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-4是由活化的Th2細胞和肥大細胞產(chǎn)生的多效性細胞因子,在免疫反應(yīng)中起著關(guān)鍵作用。IL-4的作用是在與造血細胞和非造血細胞上存在的高親和力受體復合物結(jié)合后介導的。造血細胞對IL-4的反應(yīng)是由140 kDa IL4Rα(CD124)亞基和70 kDa常見細胞因子γc鏈(CD132)組成的高親和力受體復合物介導的。
白細胞介素4受體(IL4R)也稱為CD124、IL4Rα和BSF受體,是由活化的Th2細胞和肥大細胞產(chǎn)生的I型細胞因子受體,在Th2偏向性免疫反應(yīng)、替代性巨噬細胞激活、粘膜免疫、過敏性炎癥、腫瘤進展和動脈粥樣硬化中起著重要作用。編碼的IL4R蛋白的可溶性形式可以通過另一種剪接變體或膜結(jié)合蛋白的蛋白水解產(chǎn)生,這種可溶性形式可以抑制IL4介導的細胞增殖和T細胞上調(diào)IL5。IL4R可以與IL-13Ra1結(jié)合形成對IL-4和IL-13都有反應(yīng)的II型受體。白細胞介素-4受體已被證明與SHC1相互作用。
