SARS-CoV-2是导致全球死亡率不断上升的大流行病的原因。利用质谱法(ChIRP-MS)对RNA结合蛋白的全面鉴定,我们鉴定了309种在活动感染期间与SARS-CoV-2 RNA结合的宿主蛋白。将该数据与来自其他三种RNA病毒的ChIRP-MS数据整合,定义了RNA-宿主蛋白相互作用的病毒特异性。靶向CRISPR筛选显示,大多数功能性RNA结合蛋白可以保护宿主免受病毒诱导的细胞死亡,而对七种RNA病毒的比较CRISPR筛选显示了共享的和SARS特异性的抗病毒因子。最后,通过结合以RNA为中心的方法和功能性CRISPR筛选,我们证明了SARS-CoV-2和线粒体之间的物理和功能联系,突出了这种细胞器作为抗病毒活性的一般平台。总而言之,这些数据提供了一个全面的功能性SARS-CoV-2 RNA-宿主蛋白相互作用的目录,这可能会为研究提供信息,以了解宿主-病毒界面,并提名可以靶向治疗获益的宿主途径。SARS-CoV-2 RNA的ChIRP-MS鉴定病毒RNA-宿主蛋白相互作用网络比较分析鉴定SARS特异性和多病毒RNA-蛋白复合物SARS-CoV-2相互作用组聚焦的CRISPR筛选揭示了广泛的抗病毒反应宿主线粒体作为抗SARS-CoV-2免疫的一般细胞器平台通过ChIRP-MS和CRISPR筛选对SARS-CoV-2 RNA-宿主蛋白相互作用网络的询问,与其他人类病毒如黄病毒、小核糖核酸病毒和鼻病毒相比,鉴定了对SARS-CoV-2感染特异的复合物,并强调了线粒体在介导抗病毒免疫中的作用。
SARS-CoV-2 is the cause of a pandemic with growing global mortality. Using comprehensive identification of RNA-binding proteins by mass spectrometry (ChIRP-MS), we identified 309 host proteins that bind the SARS-CoV-2 RNA during active infection. Integration of this data with ChIRP-MS data from three other RNA viruses defined viral specificity of RNA-host protein interactions. Targeted CRISPR screens revealed that the majority of functional RNA-binding proteins protect the host from virus-induced cell death, and comparative CRISPR screens across seven RNA viruses revealed shared and SARS-specific antiviral factors. Finally, by combining the RNA-centric approach and functional CRISPR screens, we demonstrated a physical and functional connection between SARS-CoV-2 and mitochondria, highlighting this organelle as a general platform for antiviral activity. Altogether, these data provide a comprehensive catalog of functional SARS-CoV-2 RNA-host protein interactions, which may inform studies to understand the host-virus interface and nominate host pathways that could be targeted for therapeutic benefit. ChIRP-MS of SARS-CoV-2 RNA identifies viral RNA-host protein interaction networks Comparative analysis identifies SARS-specific and multi-viral RNA-protein complexes SARS-CoV-2 interactome-focused CRISPR screens reveal a broad antiviral response Host mitochondria serve as a general organelle platform for anti-SARS-CoV-2 immunity Interrogation of SARS-CoV-2 RNA-host protein interaction networks by ChIRP-MS and CRISPR screens, in comparison with other human viruses such as flaviviruses, picornavirus, and rhinovirus, identifies complexes specific to SARS-CoV-2 infection and highlights the role of mitochondria in mediating antiviral immunity.
