严重急性呼吸综合征冠状病毒2(SARS-CoV-2)在感染和病毒复制过程中劫持多种人类蛋白质。为了检查是否有任何病毒蛋白采用人E3泛素连接酶,我们评估了抑制泛素蛋白酶体途径的SARS-CoV-2蛋白的稳定性。使用遗传筛选来剖析参与候选病毒蛋白质降解的分子机制,我们鉴定了人E3连接酶RNF 185作为SARS-CoV-2包膜蛋白的蛋白质稳定性调节剂。我们发现RNF 185和SARS-CoV-2包膜共定位于内质网(ER)。最后,我们证明了RNF 185的耗竭显著增加了细胞模型中SARS-CoV-2病毒的滴度。调节这种相互作用可以为新型抗病毒治疗提供机会。RNF 185是一种人E3连接酶,调节SARS-CoV-2包膜蛋白RNF 185和SARS-CoV-2包膜蛋白共定位于内质网的稳定性RNF 185的消耗显著增加细胞模型中SARS-CoV-2病毒滴度病毒学;细胞生物学
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) hijacks multiple human proteins during infection and viral replication. To examine whether any viral proteins employ human E3 ubiquitin ligases, we evaluated the stability of SARS-CoV-2 proteins with inhibition of the ubiquitin proteasome pathway. Using genetic screens to dissect the molecular machinery involved in the degradation of candidate viral proteins, we identified human E3 ligase RNF185 as a regulator of protein stability for the SARS-CoV-2 envelope protein. We found that RNF185 and the SARS-CoV-2 envelope co-localize to the endoplasmic reticulum (ER). Finally, we demonstrate that the depletion of RNF185 significantly increases SARS-CoV-2 viral titer in a cellular model. Modulation of this interaction could provide opportunities for novel antiviral therapies.
