LAG3/NFAT-Luc/Jurkat
CBP74060
I. Background | |
淋巴细胞活化基因 3 (LAG-3),又名 CD223,是一种 I 型跨膜蛋白,属于免疫球蛋白超家族 (IgSF)。LAG-3 蛋白与 CD4 有同源结构,两者的胞外区均具有四个 Ig 样结构域,但 LAG-3 在膜远端 Ig 样结构域内还含有一种额外的环状结构,使其与MHC II的亲和力较CD4高100倍。LAG-3 在活化的 T 细胞、B 细胞、浆细胞样树突状细胞 (DC) 和 NK 细胞上表达。LAG3 可结合 MHC II类 (MHC II)分子外,也可结合纤维蛋白原样蛋白 1(FGL-1)、α-突触核蛋白原纤维 (α-syn) 和凝集素半乳糖凝集素-3 (Gal-3) 以及淋巴结窦内皮细胞 C 型凝集素 (LSECtin) 。 |
