背景(Background)
白细胞介素-13受体亚基α-2也称为IL13Rα2、IL13Ra2分化簇213A2、CD213A2、CT19、IL-13R、IL13BP,是一种膜结合蛋白,在人类中由IL13Ra2基因编码。IL13Rα2与白细胞介素-13受体复合物的亚基IL13Rα1密切相关。该蛋白以高亲和力结合IL13,但缺乏任何重要的细胞质结构域,似乎不起信号介体的作用。然而,它能够调节IL13和IL4的作用,尽管它不能直接与后者结合。据报道,它在IL13的内化中也发挥了作用。IL13Rα2是细胞表面受体的一个组成部分,然而,大多数存在于细胞内池中并以可溶性形式存在,因此与IL13Rα1相比,IL13R2作为强效IL13拮抗剂起着相反的作用。它还可能通过IL13Rα2的短胞内结构域和胞质结构域与IL4Rα链之间的物理相互作用,发挥IL4依赖途径的抑制剂作用。尽管STAT信号功能失败,IL13Rα2剂量诱导TGF-β的产生和纤维化。此外,据报道,IL13Rα2在多形性胶质母细胞瘤中大量特异性过表达。
