Ebola virus Glycoprotein/GP 蛋白 (Q7T9D9, HEK293, His)

Ebola virus glycoprotein (GP1), as a receptor-binding subunit, plays a key role in the virus entry process. During late stages of infection, GP1 downregulates key host cell surface molecules, including integrins such as ITGA1-6, disrupting adhesion and potentially leading to disruption of vascular integrity. Ebola virus Glycoprotein/GP Protein (Q7T9D9, HEK293, His) is the recombinant Virus-derived Ebola virus Glycoprotein/GP protein, expressed by HEK293 , with C-His labeled tag. The total length of Ebola virus Glycoprotein/GP Protein (Q7T9D9, HEK293, His) is 605 a.a., with molecular weight of ~67.9 kDa.

埃博拉病毒糖蛋白 (GP) 的三聚体 GP1,2 复合物在病毒进入过程中发挥着关键作用，其中 GP1 充当受体结合亚基，GP2 充当膜融合亚基。在感染的后期，GP1 下调参与免疫监视和细胞粘附的关键宿主细胞表面分子的表达。这包括整合素的调节，如 ITGA1、ITGA2、ITGA3、ITGA4、ITGA5、ITGA6、ITGAV 和 ITGB1，可能导致细胞脱离并导致血管完整性破坏，从而导致感染期间出血（细胞毒性）。此外，GP1 与宿主 TLR4 相互作用，刺激单核细胞的分化和激活，导致 T 淋巴细胞的旁观者死亡。它进一步下调宿主自然杀伤细胞的功能，并抵消宿主 BST2/tetherin 的抗病毒作用，从而限制子代病毒粒子从受感染的细胞中释放。有趣的是，GP1 与 VP40 和宿主 BST2 合作，以依赖于 neddylation 的方式激活典型的 NF-kappa-B 通路。此外，GP1 作为抗 GP1,2 抗体的诱饵，有助于病毒免疫逃避，并与宿主巨噬细胞和树突状细胞相互作用，诱导细胞因子转录上调，这种效应是通过激活宿主 TLR4 介导的。

无菌粉末.

Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O.

Stored at -20°C for 2 years. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.
