While Nups primarily function at NPCs, multiple Nups function in the nucleoplasm independent of the NPC. We previously found that\n                  <jats:italic>Nup98-96<\/jats:italic>\n                  is necessary for entry into S phase in Drosophila cells, however, the mechanism is unknown. Here, we demonstrate that\n                  <jats:italic>Nup98-96<\/jats:italic>\n                  is one of only a subset of Nup genes that can promote entry into S phase. We identify that transcripts dependent on\n                  <jats:italic>Nup98-96<\/jats:italic>\n                  in Drosophila cells are enriched in cell cycle processes and that many of these transcripts are also dependent on the cell cycle regulator, E2f1. Importantly, we find that entry into S phase can be rescued by co-depleting the CycE\/CDK2 inhibitor,\n                  <jats:italic>dacapo<\/jats:italic>\n                  , in\n                  <jats:italic>Nup98-96<\/jats:italic>\n                  -depleted cells. Furthermore,\n                  <jats:italic>Nup96-98<\/jats:italic>\n                  promotes S phase entry across multiple cell and tissue types and cell cycle contexts. Critically, overexpression of\n                  <jats:italic>Nup98<\/jats:italic>\n                  has a dominant-negative effect on entry into S phase in larval salivary glands, suggesting that Nup98, not Nup96, promotes entry into S phase. Our work identifies Nup98 as a key regulator of the G1\/S transition in metazoans.\n
