Question: What is the function of the Nup153 protein?

Context: Nup153 to reforming functional nuclear envelopes
Taken together, these results showed that emerin, LBR, and several NPC components (RanBP2, Nup153, p62), but not Tpr, reconstitute around chromosomes very early in telophase prior to the recovery of nuclear import activity.
On the basis of protein domain similarity, the human nucleoporin Nup153
human Nup153 mediate nuclear import
In addition to being important to pore architecture, Nup153 is a key participant in both import and export
During the transition into mitosis, Nup153 directs proteins involved in membrane remodeling to the nuclear envelope.
Overall, the versatile nature of Nup153 underscores an emerging view of the nuclear pore at the nexus of many key cellular processes.
Nucleoporin NUP153 guards genome integrity by promoting nuclear import of 53BP1.
a nuclear pore component NUP153 as a novel factor specifically required for 53BP1 nuclear import.
The nuclear basket is composed of the 3 nucleoporins Nup153, Nup50, and Tpr, but their specific role for the structural organization of this NPC substructure is, however, not well established
The nuclear pore protein Nup153 associates with chromatin and regulates cardiac gene expression in dystrophic mdx hearts.
The nucleoporin Nup153 has been implicated in the DNA damage response, attributed to a role in promoting nuclear import of 53BP1.
Nup153 is a large (153 kD) O-linked glyco-protein which is a component of the basket structure located on the nucleoplasmic face of nuclear pore complexes.
In addition to being important to pore architecture, Nup153 is a key participant in both import and export.
Finally, we show that the C-terminal part of NUP153 is required for effective 53BP1 nuclear import, and that 53BP1 is imported to the nucleus through the NUP153-importin-β interplay.
Our data define the structure-function relationships within this emerging 53BP1-NUP153/importin-β pathway and implicate this mechanism in the maintenance of genome integrity.
Here, we provide the complete results of this screen as an information resource, and validate and functionally characterize one of the identified 'hits': a nuclear pore component NUP153 as a novel factor specifically required for 53BP1 nuclear import.
