cGAS 蛋白, Mouse (Biotinylated, Avi)

cGAS Protein, Mouse (Biotinylated, Avi) is the recombinant mouse-derived cGAS protein, expressed by E. coli, with Avi tag.

cGAS 蛋白是一种核苷酸转移酶，通过催化 ATP 和 GTP 形成环 GMP-AMP (2',3'-cGAMP)，在先天免疫中发挥关键作用。作为关键的 DNA 传感器，cGAS 直接结合双链 DNA (dsDNA)，诱导 2',3'-cGAMP 的合成，这是激活 STING1 的第二信使，从而产生 I 型干扰素并触发免疫反应。cGAS 可识别弯曲的长 dsDNA，充当外来 DNA 传感器，检测来自病毒、逆转录病毒、细菌和中性粒细胞胞外陷阱 (NET) 的 DNA 的存在。此外，cGAS 对细胞应激过程中释放的内源 DNA 做出反应，导致无菌炎症。它通过与胞质染色质片段结合来调节细胞衰老，并参与对基因组不稳定和双链 DNA 断裂的炎症反应。cGAS 还参与感知翻译应激，其激活会抑制 DNA 损伤时的同源重组修复。人类 cGAS 表现出物种特异性的 DNA 识别机制，可以对病原体做出更精细的反应。
