Importin-β modulates the permeability of the nuclear pore complex in a Ran-dependent manner
Soluble karyopherins of the importin-β (impβ) family use RanGTP to transport cargos directionally through the nuclear pore complex (NPC). Whether impβ or RanGTP regulate the permeability of the NPC itself has been unknown. In this study, we identify a stable pool of impβ at the NPC. A subpopulation of this pool is rapidly turned-over by RanGTP, likely at Nup153. Impβ, but not transportin-1 (TRN...
متن کاملTranscriptional regulation at the nuclear pore complex.
The nonrandom spatial distribution of chromosomes and genes in the eukaryotic nucleus has been appreciated for decades, although a detailed understanding of the functional role of such positioning has remained illusive. The most prominent structural feature of the nucleus is the nuclear periphery, classically considered as a zone of gene repression caused by the presence of heterochromatin and ...
متن کاملNo waiting at the nuclear pore complex
Airport security checkpoints might take a lesson from the nuclear pore complex (NPC), where, according to Dange et al., there are no long lines and no slowdown despite the hubbub around them. The group used single-molecule video microscopy, with a localization precision of about the width of a protein, to track single molecules of labeled, cargo-carrying receptors entering the NPC in vivo. They...
متن کاملA gradient of affinity for the karyopherin Kap95p along the yeast nuclear pore complex.
Karyopherins (Kaps) transport cargo across the nuclear pore complex (NPC) by interacting with nucleoporins that contain phenylalanine-glycine (FG) peptide repeats (FG Nups). As a test of the "affinity gradient" model for Kap translocation, we measured the apparent affinity of Kap95p to FG Nups representing three distinct regions of the S. cerevisiae NPC. We find that the affinity of Kap95p-Kap6...
متن کاملRan-unassisted Nuclear Migration of a 97-kD Component of Nuclear Pore–targeting Complex
A 97-kD component of nuclear pore-targeting complex (the beta-subunit of nuclear pore-targeting complex [PTAC]/importin/karyopherin) mediates the import of nuclear localization signal (NLS)-containing proteins by anchoring the NLS receptor protein (the alpha-subunit of PTAC/importin/karyopherin) to the nuclear pore complex (NPC). The import requires a small GTPase Ran, which interacts directly ...
