Despite their importance, few host factors implicated in paramyxovirus infection are known. Using a recombinant SeV expressing destabilized GFP (rSeVC\n                  <jats:sup>dseGFP<\/jats:sup>\n                  ) in a loss-of-function CRISPR screen, we identified the CMP-sialic acid transporter (CST) gene\n                  <jats:italic>SLC35A1<\/jats:italic>\n                  and the UDP-galactose transporter (UGT) gene\n                  <jats:italic>SLC35A2<\/jats:italic>\n                  as essential for paramyxovirus infection.\n                  <jats:italic>SLC35A1<\/jats:italic>\n                  knockout (KO) cells showed significantly reduced binding and infection of SeV, NDV and MuV due to the lack of cell surface sialic acids, which act as their receptors. However,\n                  <jats:italic>SLC35A2<\/jats:italic>\n                  KO cells revealed unknown critical roles for this factor in virus-cell and cell-to-cell fusion events during infection with different paramyxoviruses. While the UGT was essential for virus-cell fusion during SeV entry to the cell, it was not required for NDV or MuV entry. Importantly, the UGT promoted the formation of larger syncytia during MuV infection, suggesting a role in cell-to-cell virus spread. Our findings demonstrate that paramyxoviruses can bind to or enter A549 cells in the absence of canonical galactose-bound sialic-acid decorations and show that the UGT facilitates paramyxovirus fusion processes involved in entry and spread.\n                <\/jats:p>","DOI":"10.1101\/2024.08.27.609835","type":"posted-content","created":{"date-parts":[[2024,8,30]],"date-time":"2024-08-30T09:40:45Z","timestamp":1725010845000},"source":"Crossref","is-referenced-by-count":0,"title":["<i>SLC35A2<\/i>\n                  modulates paramyxovirus fusion events during infection"],"prefix":"10.64898","author":[{"given":"Yanling","family":"Yang","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuchen","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Danielle E.","family":"Campbell","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Heng-Wei","family":"Lee","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Leran","family":"Wang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Megan","family":"Baldridge","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7669-6572","authenticated-orcid":false,"given":"Carolina B.","family":"L\u00f3pez","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"54368","reference":[{"key":"2024090203200833000_2024.08.27.609835v1.1","doi-asserted-by":"publisher","DOI":"10.1093\/infdis\/jiad123"},{"key":"2024090203200833000_2024.08.27.609835v1.2","doi-asserted-by":"publisher","DOI":"10.3390\/pathogens11121419"},{"key":"2024090203200833000_2024.08.27.609835v1.3","doi-asserted-by":"publisher","DOI":"10.1074\/jbc.REV119.009961"},{"key":"2024090203200833000_2024.08.27.609835v1.4","doi-asserted-by":"publisher","DOI":"10.1038\/nrmicro3346"},{"key":"2024090203200833000_2024.08.27.609835v1.5","doi-asserted-by":"publisher","DOI":"10.3390\/v4040613"},{"key":"2024090203200833000_2024.08.27.609835v1.6","doi-asserted-by":"publisher","DOI":"10.1099\/vir.0.82150-0"},{"key":"2024090203200833000_2024.08.27.609835v1.7","doi-asserted-by":"publisher","DOI":"10.1128\/JVI.02288-20"},{"key":"2024090203200833000_2024.08.27.609835v1.8","doi-asserted-by":"publisher","DOI":"10.1128\/JVI.02617-06"},{"key":"2024090203200833000_2024.08.27.609835v1.9","doi-asserted-by":"publisher","DOI":"10.1083\/jcb.200305130"},{"key":"2024090203200833000_2024.08.27.609835v1.10","doi-asserted-by":"publisher","DOI":"10.1016\/j.coviro.2014.01.005"},{"key":"2024090203200833000_2024.08.27.609835v1.11","doi-asserted-by":"publisher","DOI":"10.1016\/j.mam.2012.12.004"},{"key":"2024090203200833000_2024.08.27.609835v1.12","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.1608383113"},{"key":"2024090203200833000_2024.08.27.609835v1.13","doi-asserted-by":"publisher","DOI":"10.1128\/JVI.00344-19"},{"key":"2024090203200833000_2024.08.27.609835v1.14","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.78.9.5406"},{"key":"2024090203200833000_2024.08.27.609835v1.15","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.77.10.5693"},{"key":"2024090203200833000_2024.08.27.609835v1.16","doi-asserted-by":"publisher","DOI":"10.1007\/s10719-012-9431-0"},{"key":"2024090203200833000_2024.08.27.609835v1.17","doi-asserted-by":"publisher","DOI":"10.1128\/cmr.00168-19"},{"key":"2024090203200833000_2024.08.27.609835v1.18","doi-asserted-by":"crossref","unstructured":"Li G , De Clercq E .
