Despite increasing recognition of PTMs as dynamic regulators of infection, their full functional breadth and therapeutic potential remain incompletely defined. Here, we provide a comprehensive, PTM-centric synthesis of SARS-CoV-2 pathogenesis, detailing how phosphorylation, ubiquitination, SUMOylation, glycosylation, acetylation, succinylation, ISGylation, and ADP-ribosylation cooperatively shape virus\u2013host interplay. We dissect the mechanistic roles of individual modifications, such as phosphorylation-mediated transitions in nucleocapsid function, ubiquitin-driven degradation of immune factors, and SUMOylation-guided viral assembly, while revealing higher-order regulatory circuits and crosstalk among PTMs. Additionally, we highlight emerging computational tools for PTM site prediction and identify shared enzymatic nodes exploitable for host-directed antiviral strategies. This integrative framework positions PTMs as not merely bystanders but as central modulators of viral fitness and host vulnerability, offering novel avenues for therapeutic intervention against SARS-CoV-2 and future pandemic threats.<\/jats:p>","DOI":"10.3389\/fmicb.2026.1748470","type":"journal-article","created":{"date-parts":[[2026,2,10]],"date-time":"2026-02-10T07:16:08Z","timestamp":1770707768000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":3,"title":["Rewriting the viral script: post-translational modifications orchestrating SARS-CoV-2 pathogenesis and immune evasion"],"prefix":"10.3389","volume":"17","author":[{"given":"Jie","family":"Qu","sequence":"first","affiliation":[{"name":"Department of Cadre Ward, The First Hospital of Jilin University","place":["Changchun, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Minglong","family":"Liu","sequence":"additional","affiliation":[{"name":"Department of Cadre Ward, The First Hospital of Jilin University","place":["Changchun, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chen","family":"Zhou","sequence":"additional","affiliation":[{"name":"General Department, The First Hospital of Jilin University (The Eastern Division)","place":["Changchun, China"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2026,2,10]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1128\/jvi.01969-20","article-title":"The SARS-CoV-2 conserved macrodomain is a mono-ADP-ribosylhydrolase","volume":"95","author":"Alhammad","year":"2021","journal-title":"J.
