Integrating the protein- and RNA-interactomes, we found that SARS-CoV-2 RNA and its N protein closely interacted with stress granules including 40 core factors, of which we specifically validated G3BP1, IGF2BP1, and MOV10 using RIP and Co-IP assays. Combining CRISPR screening results, we further identified 86 antiviral and 62 proviral factors and associated drugs. Using network diffusion, we found additional 44 interacting proteins including two proviral factors previously validated. Furthermore, we showed that this atlas could be applied to identify the complications associated with COVID-19.
本研究整合蛋白质相互作用组与RNA相互作用组数据,发现新型冠状病毒(SARS-CoV-2)RNA及其核衣壳蛋白(N蛋白)可与应激颗粒(stress granules)发生紧密相互作用,涉及40种核心因子;其中我们通过RNA免疫沉淀(RIP)与免疫共沉淀(Co-IP)实验,特异性验证了G3BP1、IGF2BP1及MOV10这三种因子。结合CRISPR筛选结果,我们进一步鉴定得到86种抗病毒因子与62种促病毒因子及其关联药物。借助网络扩散分析,我们额外发现了44种相互作用蛋白,其中包含2种此前已被验证的促病毒因子。此外,本研究证实该相互作用图谱可用于识别新型冠状病毒肺炎(COVID-19)相关并发症。
