The global emergence of azole resistance further increases treatment failure, underscoring the urgent need for antifungals with novel mechanisms of action. The fungal cell cycle is essential for viability and represents an attractive but underexplored target. In\n                      <jats:italic toggle=\"yes\">A. fumigatus<\/jats:italic>\n                      , progression from G2 to M phase requires interaction between the phosphatase NimT and cyclin-dependent kinase NimX. Here, we characterize the role of this interaction and its inhibition by 2-fluoro-4-hydroxybenzonitrile (compound 1), a small molecule that targets the human Cdc25B\u2013Cdk2 interface. Using mutagenesis, we show that NimT residues Arg438 and Arg442 are critical for NimT\u2013NimX binding and confirm they are essential for viability. A co-immunoprecipitation assay demonstrates that compound 1 disrupts the interaction, while live-cell imaging shows that this inhibition arrests cell cycle progression. Our findings provide mechanistic insight into fungal mitosis and highlight cell cycle regulators as promising antifungal drug targets.\n                    <\/jats:p>\n                    <jats:sec>\n                      <jats:title>IMPORTANCE<\/jats:title>\n                      <jats:p>\n                        Invasive aspergillosis has high mortality and limited treatment options, threatened by rising drug resistance. Targeting the fungal cell cycle represents an unexplored strategy for antifungal drug development. The dynamic interaction between NimT and NimX is critical to the fungal duplication cycle. Here, we show evidence that, unlike in\n                        <jats:italic toggle=\"yes\">Schizosaccharomyces pombe<\/jats:italic>\n                        , relocation of NimT from the nucleus to the cytoplasm mid-interphase is the switching event that causes activation of NimX and allows the cell cycle to progress. We also show that disruption of the NimT\u2013NimX interaction can be achieved using a reversible small-molecule inhibitor that arrests the fungal duplication cycle, highlighting mitotic regulators as promising antifungal drug targets.\n                      <\/jats:p>\n                    <\/jats:sec>\n                  <\/jats:sec>","DOI":"10.1128\/mbio.03563-25","type":"journal-article","created":{"date-parts":[[2026,4,29]],"date-time":"2026-04-29T13:01:07Z","timestamp":1777467667000},"update-policy":"https:\/\/doi.org\/10.1128\/asmj-crossmark-policy-page","source":"Crossref","is-referenced-by-count":0,"title":["A protein\u2013protein interaction inhibitor arrests the cell cycle in\n                    <i>Aspergillus fumigatus<\/i>"],"prefix":"10.1128","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8717-2574","authenticated-orcid":false,"given":"I.
