Importin-9 recognizes the winged-helix fold of ETS transcription factors to mediate nuclear import

Proceedings of the National Academy of Sciences, Volume 123, Issue 18, May 2026. <br/>SignificanceNuclear import is essential for transcription factor function. However, many nuclear proteins lack recognizable nuclear localization signals (NLSs), leaving their trafficking mechanisms unresolved. Here, we identify the winged-helix DNA-…
