However, most virus-focused CRISPR screens utilize selection strategies that limit the ability to identify genes important for infection. Here, we developed a CRISPR screening pipeline to identify cellular determinants of human cytomegalovirus (HCMV) infection based on virally induced remodeling of cellular antibody affinity (VIRCAA), which is scalable for large libraries and can identify cellular genes that impact HCMV infection at different life cycle stages. We utilized this pipeline to interrogate proteomic and transcriptomic datasets associated with the HCMV UL26 protein, which blocks antiviral signaling during infection. We find that JUNB drives antiviral gene expression, induces protein ISGylation, and suppresses diverse viral infections. Further, UL26 interacts with JUNB and suppresses JUNB-mediated condensation of viral DNA replication compartments. These results highlight the VIRCAA pipeline\u2019s utility for identifying important determinants of viral infection.<\/jats:p>","DOI":"10.1073\/pnas.2534154123","type":"journal-article","created":{"date-parts":[[2026,3,30]],"date-time":"2026-03-30T19:02:15Z","timestamp":1774897335000},"update-policy":"https:\/\/doi.org\/10.1073\/pnas.cm10313","source":"Crossref","is-referenced-by-count":0,"title":["Cellular antibody affinity\u2013based CRISPR screening identifies JUNB as a broadly acting antiviral factor"],"prefix":"10.1073","volume":"123","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4461-2650","authenticated-orcid":false,"given":"Nicole C.","family":"Waild","sequence":"first","affiliation":[{"name":"Department of Biochemistry and Biophysics, University of Rochester School of Medicine and Dentistry","place":["Rochester"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5305-5783","authenticated-orcid":false,"given":"Jessica H.","family":"Ciesla","sequence":"additional","affiliation":[{"name":"Department of Biochemistry and Biophysics, University of Rochester School of Medicine and Dentistry","place":["Rochester"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0973-3038","authenticated-orcid":false,"given":"Xenia L.","family":"Schafer","sequence":"additional","affiliation":[{"name":"Department of Biochemistry and Biophysics, University of Rochester School of Medicine and Dentistry","place":["Rochester"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5379-9440","authenticated-orcid":false,"given":"Joshua","family":"Munger","sequence":"additional","affiliation":[{"name":"Department of Biochemistry and Biophysics, University of Rochester School of Medicine and Dentistry","place":["Rochester"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"341","published-online":{"date-parts":[[2026,3,30]]},"reference":[{"key":"e_1_3_4_1_2","doi-asserted-by":"publisher","DOI":"10.1038\/s41467-018-07901-8"},{"key":"e_1_3_4_2_2","doi-asserted-by":"publisher","DOI":"10.1038\/nbt.3437"},{"key":"e_1_3_4_3_2","doi-asserted-by":"publisher","DOI":"10.1038\/nrmicro.2017.29"},{"key":"e_1_3_4_4_2","doi-asserted-by":"publisher","DOI":"10.1007\/978-1-0716-1111-1_13"},{"key":"e_1_3_4_5_2","doi-asserted-by":"publisher","DOI":"10.1038\/s41586-024-07503-z"},{"key":"e_1_3_4_6_2","doi-asserted-by":"publisher","DOI":"10.1371\/journal.ppat.1008777"},{"key":"e_1_3_4_7_2","doi-asserted-by":"publisher","DOI":"10.1038\/s41587-021-01059-3"},{"key":"e_1_3_4_8_2","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.1806305115"},{"key":"e_1_3_4_9_2","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.1814850116"},{"key":"e_1_3_4_10_2","doi-asserted-by":"publisher","DOI":"10.1002\/rmv.655"},{"key":"e_1_3_4_11_2","doi-asserted-by":"publisher","DOI":"10.1002\/rmv.2034"},{"key":"e_1_3_4_12_2","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM199203053261003"},{"key":"e_1_3_4_13_2","doi-asserted-by":"publisher","DOI":"10.3390\/tropicalmed9020049"},{"key":"e_1_3_4_14_2","doi-asserted-by":"publisher","DOI":"10.1128\/CMR.00043-19"},{"key":"e_1_3_4_15_2","first-page":"389","article-title":"\u201cCytomegalovirus\u201d","author":"Goodrum F.","unstructured":"F.
