Paper visualizing traffic through nuclear pores unlocks the full potential of #MINFLUX:
2-color 3D tracking with sub-ms time resolution and single-digit nm localization precision 💪

I’m excited to share our latest research from the Musser Lab, published today in Nature. Using two-color 3D MINFLUX, we directly visualized nuclear import and export events through transport-active nuclear pores. (1/5)

Overlapping nuclear import and export paths unveiled by two-colour MINFLUX - Nature

High spatiotemporal precision tracking using 3D MINFLUX shows that nuclear import and export occur in overlapping regions of the central pore, providing insight into transport across the nuclear pore ...

How is transport directionality achieved through the #trypanosome nuclear pore complex? The current model is symmetrical, but this study reveals that the trypanosome #NuclearPore has an asymmetrical architecture, with conserved hubs that direct mRNA transport 🧪 @plosbiology.org plos.io/3Q36QV2

Expansion microscopy identifies novel asymmetric pore proteins. The images show proExM of cell lines co-expressing epitope-tagged versions of NUP76 (top; magenta), NUP149 (middle; magenta), or NUP140 (bottom; magenta) in combination with NUP110 (green). Images were deconvolved (20 iterations for NUP149 and NUP76; 60 iterations for NUP140) and single planes of the nuclei are shown.

Exportin-1 functions as an adaptor for transcription factor-mediated docking of chromatin at the nuclear pore complex

Many genes physically interact with the nuclear pore complex (NPC), which requires transcription factors (TFs). Ge et al. show that the exportin Crm1 binds TFs and nuclear pore proteins to dock chroma...

#SMLM #RESI #DNAPAINT #Microscopy #nuclearpore

DNA-PAINT and RESI imaging of ALFA-tagged nuclear pore protein Nup96 using the RESI anti-ALFA kit. For RESI imaging, four Exchange-PAINT rounds were performed using a mixture of anti-ALFA single-domain antibodies carrying docking strands F1, F2, F3, and F4 (10,000 frames per round,100 ms integration time, ~ 80 min total imaging time). Image post-processing was carried out using the open-source DNA-PAINT analysis software Picasso's RESI module.
For classic DNA-PAINT, all four imager strands were added to the sample simultaneously.
