proteomics and biochemistry
Recorded terms: data-independent acquisition phosphoproteomics; phosphoproteomics by liquid chromatography mass spectrometry
Kinase substrate specificity profiling assigns the phosphorylation cluster in the SARS-CoV-2 nucleocapsid SR-rich domain to a cascade initiated by SRPK1 and SRPK2 and extended by GSK-3 and casein kinase 1, whose inhibition suppresses coronavirus replication.
A time-resolved phosphoproteomic survey of SARS-CoV-2-infected cells showing that infection acts mainly through signalling rather than protein abundance, activating casein kinase II and the p38 cascade while shutting down mitotic kinases, and converting that kinase profile into inhibitors with antiviral activity.
