Description

The abstract shows KPNB1 is recruited into pathological TDP-43/FG-Nup co-aggregates where it acts therapeutically, but doesn’t explain how KPNB1 distinguishes between normal nuclear pore complexes and disease aggregates. Understanding this selectivity is crucial for therapeutic targeting without disrupting normal nucleocytoplasmic transport.
