FGL1 蛋白, Human (HEK293, His, solution)

FGL1 protein is the main ligand of LAG3 and can inhibit antigen-specific T cell activation, mediating the inhibitory function of LAG3 independently of MHC-II binding. FGL1 is secreted by liver cells and contributes to their growth. FGL1 Protein, Human (HEK293, His, solution) is the recombinant human-derived FGL1 protein, expressed by HEK293 , with C-6*His labeled tag.

FGL1 蛋白作为一种免疫抑制分子，通过作为 LAG3 的主要配体对抗原特异性 T 细胞激活发挥抑制作用。它在独立于 MHC II 类 (MHC-II) 结合介导 LAG3 的 T 细胞抑制功能中发挥着关键作用。除了其免疫调节作用外，FGL1 还由肝细胞分泌，有助于其生长。FGL1 作为同二聚体存在，通过其纤维蛋白原 C 末端结构域与 LAG3 相互作用，特异性结合 LAG3 的 Ig 样结构域 1 和 2。研究中详细介绍了这种分子相互作用，强调了 FGL1 在调节免疫反应和肝细胞生长中的重要性，强调了其在 T 细胞激活和肝功能调节中发挥关键作用的潜力。
