分子别名(Synonym)
IL4R,CD124,IL4RA
表达区间及表达系统(Source)
Biotinylated Human IL-4 R alpha, Avitag,His Tag (ILR-H82E9) is expressed from human 293 cells (HEK293). It contains AA Met 26 - His 232 (Accession # NP_000409.1).
Predicted N-terminus: Met 26
蛋白结构(Molecular Characterization)

This protein carries an Avi tag (Avitag™) at the C-terminus, followed by a polyhistidine tag.
The protein has a calculated MW of 26.9 kDa. The protein migrates as 35-55 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
标记(Labeling)
Biotinylation of this product is performed using Avitag™ technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.
蛋白标记度(Protein Ratio)
Passed as determined by the HABA assay / binding ELISA.
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-4受体(IL4R/CD124/IL4Rα)作为I型细胞因子受体,由活化Th2细胞和肥大细胞表达,通过结合造血/非造血细胞表面的高亲和力受体复合物介导IL-4多效性功能:在经典I型通路中,140kDa的IL4Rα亚基与70kDa共同细胞因子受体γ链(γc/CD132)组装成信号复合体,激活JAK-STAT通路调控Th2型免疫应答、替代性巨噬细胞活化及黏膜免疫;其II型受体模式则由IL4Rα与IL13Rα1形成异源二聚体,可同时响应IL-4/IL-13信号,参与过敏性炎症、肿瘤进展及动脉粥样硬化形成。该受体产生的可溶性形式(经选择性剪接或膜蛋白蛋白酶解生成)能抑制IL-4介导的细胞增殖与T细胞IL-5上调,并与SHC1信号转导蛋白存在相互作用。
