Interferon (IFN)-stimulated gene 15 (ISG15) regulates diverse cellular processes, including antiviral immunity, through its conjugation to target proteins (ISGylation). Increasing evidence suggests that ISGylation can also reshape cellular metabolism; however, how viruses counteract ISGylation-me...
Alphaviruses are mosquito-vectored, positive-strand RNA viruses causing rheumatic and neurological diseases. Like all RNA viruses, they encode an RNA-dependent RNA polymerase (RdRp, nsP4). Purification of an nsP4 derivative capable of processive RNA synthesis from a heteropolymeric template has been...
Human coronaviruses (hCoV) have become a threat to global health and society, as evident from the SARS outbreak in 2002 caused by SARS-CoV-1 and the most recent COVID-19 pandemic caused by SARS-CoV-2. Despite high sequence similarity between SARS-CoV-1 and -2, each strain has distinctive virulence. ...
