主 题:glycosylation mass spectrometry nucleocapsid protein post-translational modification SARS-CoV-2
摘 要:The devastating coronavirus disease 2019(COVID-19)pandemic has prompted worldwide efforts to study structural biological traits of severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)and its viral *** to the Spike protein,which is the primary target for currently available vaccines or antibodies,knowledge about other virion structural components is *** high-resolution mass spectrometry,we report a comprehensive post-translational modification(PTM)analysis of nucleocapsid phosphoprotein(NCP),the most abundant structural component of the SARS-CoV-2 *** addition to phosphoryl groups,we show that the SARS-CoV-2 NCP is decorated with a variety of PTMs,including N-glycans and *** on newly identified PTMs,refined protein structural models of SARS-CoV-2 NCP were proposed and potential immune recognition epitopes of NCP were aligned with *** data can facilitate the design of novel vaccines or therapeutics targeting NCP,as valuable alternatives to the current vaccination and treatment paradigm that is under threat of the ever-mutating SARS-CoV-2 Spike protein.
