FG-repeat nucleoporins at the center of the nuclear pore complex (NPC) are highly modified with O-GlcNAc. In this issue, Yoo and Mitchison (2021. J. Cell Biol.https://doi.org/10.1083/jcb.202010141) use optogenetic probes to show that O-GlcNAc enhances permeability of the NPC, accelerating transport in both directions.
