Active, GTP-bound RAN stimulates PNET2 oligomerization, potentially promoting phase separation that drives nuclear membrane expansion in plants.
- Why it matters: Plant cells need mechanisms to maintain nuclear envelope architecture and genome stability, but how this integrity is regulated is not well understood.
- What they did: The study identified PNET2 as a scaffold that cooperates with KAKU4 and CROWDED NUCLEI 1 at the nuclear lamina, using biochemical and structural modeling plus genetic pathway tests with RAN.
- The result: PNET2 loss disrupts nuclear membrane structure and sensitizes cells to DNA damage, while PNET2 and RAN act in a shared pathway required for nuclear membrane integrity.
