Previous BioID experiments targeting the nucleoporin (NUP) NUP158 (PMID: 36410438; PXD031245), as well as NUP110, NUP76, NUP96 (PMID: 39206942; PXD047268)and NUP75, transport factors MEX67 and Ran(PXD055934), indicated that proximity labelling delivers highly specific interactome data in the confined localisation of the nuclear pore, with a labelling radius well below the size of the nuclear pore. The resulting proximity data allowed to assign NUPs and nuclear transport factors to specific subregions of the pore. Here we extended this approach to target NUP98.
