PRMT5直接诱导cGAS甲基化,抑制cGAS介导的抗病毒免疫。环状GMP-AMP合成酶(CGAS)是一种重要的DNA感受器,它能感知胞质中的双链DNA并激活抗病毒反应。然而,cGAS的翻译后修饰仍不完全清楚,其是否存在精氨酸甲基化修饰也尚不清楚。在此,我们鉴定了精氨酸甲基转移酶5(PRMT5)是cGAS的直接结合伙伴,它催化了cGAS在Arg124残基上的精氨酸对称二甲基化。进一步的研究表明,PRMT5对cGAS的甲基化通过阻断cGAS的DNA结合能力来减弱cGAS介导的抗病毒免疫反应。口服PRMT5抑制剂可显著保护小鼠免受HSV-1感染,延长感染小鼠的存活时间。因此,我们的研究结果揭示了PRMT5对cGAS介导的抗病毒免疫反应的重要调节作用,并通过调节PRMT5提供了一种潜在的抗病毒策略。
PRMT5 directly induces methylation of cGAS and inhibits cGAS-mediated antiviral immunity. Cyclic GMP-AMP synthase (cGAS) functions as an essential DNA sensor, which senses the cytoplasmic double-stranded DNA and activates the antiviral response. However, the posttranslational modification of cGAS remains to be fully understood and whether it has arginine methylation modification remains unknown. Here, we identified protein arginine methyltransferase 5 (PRMT5) as a direct binding partner of cGAS, and it catalyzed the arginine symmetrical dimethylation of cGAS at the Arg124 residue. Further investigation demonstrated that methylation of cGAS by PRMT5 attenuated cGAS-mediated antiviral immune response by blocking the DNA binding ability of cGAS. Oral administration of PRMT5 inhibitors significantly protected mice from HSV-1 infection and prolonged the survival time of these infected mice. Therefore, our findings revealed an essential regulatory effect of PRMT5 on cGAS-mediated antiviral immune response and provided a promising potential antiviral strategy by modulating PRMT5.
