Loss of nuclear pore complex (NPC) proteins, transcription factors (TFs), histone modification enzymes, Mediator, and factors involved in mRNA export disrupts the physical interaction of chromosomal sites with NPCs. Conditional inactivation and ectopic tethering experiments support a direct role for the TFs Gcn4 and Nup2 in mediating interaction with the NPC but suggest an indirect role for factors involved in mRNA export or transcription. A conserved “positioning domain” within Gcn4 controls interaction with the NPC and inter-chromosomal clustering and promotes transcription of target genes. Such a function may be quite common; a comprehensive screen reveals that tethering of most yeast TFs is sufficient to promote targeting to the NPC. While some TFs require Nup100, others do not, suggesting two distinct targeting mechanisms. These results highlight an important and underappreciated function of TFs in controlling the spatial organization of the yeast genome through interaction with the NPC. Brickner et al. show that transcription factors (TFs) control positioning of genes through interaction with the nuclear pore complex. A “positioning domain” from one TF promotes interaction with the pore, and a global screen reveals that most yeast TFs mediate targeting to the NPC using at least two different pathways.
