含三方基序的蛋白5α(TRIM5α)是一种细胞抗病毒限制因子,可防止逆转录病毒复制的早期事件。由于与衣壳格子高度特异的相互作用,TRIM5α的活性被认为仅限于逆转录病毒。与目前的理解相反,我们表明人类和恒河猴TRIM5α都抑制了特定黄病毒的复制。森林脑炎复合体中的多种病毒对依赖于α的限制很敏感,但蚊媒黄病毒,包括黄热病、登革热和寨卡病毒,是耐药的。TRIM5α通过与病毒蛋白酶NS2B/3结合来抑制复制,促进其K48连接的泛素化和蛋白酶体的降解。重要的是,TRIM5α有助于干扰素-I对人类细胞中敏感的黄病毒的抗病毒作用。因此,TRIM5α在识别不同的病毒家族方面具有显著的可塑性,并有可能影响人类对全球关注的新兴黄病毒的易感性。由于与衣壳高度特异的相互作用,TRIM5α的抗病毒活性被认为仅限于逆转录病毒。在这里,希拉梅尔等人。证明TRIM5α通过结合和降解病毒蛋白酶来限制特定黄病毒的复制。
Tripartite motif-containing protein 5α (TRIM5α) is a cellular antiviral restriction factor that prevents early events in retrovirus replication. The activity of TRIM5α is thought to be limited to retroviruses as a result of highly specific interactions with capsid lattices. In contrast to this current understanding, we show that both human and rhesus macaque TRIM5α suppress replication of specific flaviviruses. Multiple viruses in the tick-borne encephalitis complex are sensitive to TRIM5α-dependent restriction, but mosquito-borne flaviviruses, including yellow fever, dengue, and Zika viruses, are resistant. TRIM5α suppresses replication by binding to the viral protease NS2B/3 to promote its K48-linked ubiquitination and proteasomal degradation. Importantly, TRIM5α contributes to the antiviral function of IFN-I against sensitive flaviviruses in human cells. Thus, TRIM5α possesses remarkable plasticity in the recognition of diverse virus families, with the potential to influence human susceptibility to emerging flaviviruses of global concern. The antiviral activity of TRIM5α is thought to be limited to retroviruses as a result of highly specific interactions with capsid lattices. Here, Chiramel et al. demonstrate that TRIM5α restricts replication of specific flaviviruses by binding and degrading the viral protease.
