Nsp5 protease
WebNirmatrelvir is a SARS-CoV-2 main protease (M pro, 3CLpro, nsp5 protease) inhibitor while ritonavir is an HIV-1 protease inhibitor and strong CYP3A inhibitor. Nirmatrelvir is the main active agent in the formulation, while ritonavir inhibits the metabolism of nirmatrelvir and thereby strengthens its activity. Web26 nov. 2024 · The genome of SARS-CoV-2 encodes for two viral cysteine proteases; nsp3 (papain-like protease) and nsp5 (main protease) . The main protease (M pro ) of SARS-CoV-2; also named chymotrypsin-like protease (3CLpr), plays a crucial role in the viral life cycle, cleaving the initial polyproteins translated from the viral RNA at at least 11 of its 14 …

Web14 apr. 2024 · SARS-CoV-2 interferes with antigen presentation by downregulating MHC II on antigen presenting cells, but the mechanism mediating this process is unelucidated. Herein, analysis of protein and gene expression in human antigen presenting cells reveals that MHC II is downregulated by the SARS-CoV-2 main protease, NSP5. This … Web28 apr. 2024 · The nonstructural protein nsp5 is a 3C-like protease of coronavirus, and our previous study showed that PDCoV nsp5 inhibits type I interferon (IFN) production. …
Web26 aug. 2024 · Drugging the proteases in SARS-CoV-2 is therefore a current focus of concerted global academic and pharma efforts (Ghosh et al, 2024). SARS-CoV-2 encodes two proteases, the papain-like protease (PLpro, encoded within nsp3) and 3-chymotrypsin-like “main” protease (3CLpro or Mpro, encoded by nsp5). Web2 feb. 2024 · As an essential enzyme of SARS-CoV-2, main protease (MPro) triggers acute toxicity to its human cell host, an effect that can be alleviated by an MPro inhibitor. Using this toxicity alleviation, we developed an effective method that allows a bulk analysis of the cellular potency of MPro inhibitors. This novel assay is advantageous over an antiviral …
WebThe protease is important in the processing of the coronavirus replicase polyprotein . It is the main protease in coronaviruses and corresponds to nonstructural protein 5 (nsp5). … Web13 feb. 2024 · Nonstructural protein 5 (Nsp5) is the main protease of SARS-CoV-2 that cleaves viral polyproteins into individual polypeptides necessary for viral replication. Here, we show that Nsp5 binds and cleaves human tRNA methyltransferase 1 (TRMT1), a host enzyme required for a common post-transcriptional modification in tRNAs. Human cells …
WebOur results show that NSP5 can significantly reduce the expression of a subset of immune response genes such as IL-6, IL-1β, and IFNβ, which requires NSP5’s protease activity. We also found that NSP5 can inhibit Sendai virus-, RNA sensor-, and DNA sensor-mediated induction of IFNβ promoter, block the IFN response pathway, and reduce the expression …
