text: Nucleocytoplasmic transport occurs exclusively through nuclear pore complexes
(NPCs) embedded in pores formed by inner and outer nuclear membrane fusion. The
mechanism for de novo pore and NPC biogenesis remains unclear. Reticulons (RTNs)
and Yop1/DP1 are conserved membrane protein families required to form and maintain
the tubular endoplasmic reticulum (ER) and the postmitotic nuclear envelope. In
this study, we report that members of the RTN and Yop1/DP1 families are required
for nuclear pore formation. Analysis of Saccharomyces cerevisiae prp20-G282S and
nup133Δ NPC assembly mutants revealed perturbations in Rtn1–green fluorescent
protein (GFP) and Yop1-GFP ER distribution and colocalization to NPC clusters.
Combined deletion of RTN1 and YOP1 resulted in NPC clustering, nuclear import
defects, and synthetic lethality with the additional absence of Pom34, Pom152,
and Nup84 subcomplex members. We tested for a direct role in NPC biogenesis using
Xenopus laevis in vitro assays and found that anti-Rtn4a antibodies specifically
inhibited de novo nuclear pore formation. We hypothesize that these ER membrane–bending
proteins mediate early NPC assembly steps.
