Besides assembling nuclear pore complexes, the conduits of nuclear transport, many nucleoporins also contribute to chromatin organization and gene expression, with critical roles in development and pathologies. We previously reported that Nup133 and Seh1, two components of the Y-complex subassembly of the nuclear pore scaffold, are dispensable for mouse embryonic stem cell viability but required for their survival during neuroectodermal differentiation. Here, a transcriptomic analysis revealed that Nup133 regulates a subset of genes at early stages of neuroectodermal differentiation, including Lhx1 and Nup210l, which encodes a newly validated nucleoporin. These genes are also misregulated in Nup133ΔMid neuronal progenitors, in which nuclear pore basket assembly is impaired. However, a four-fold reduction of Nup133 levels, despite also affecting basket assembly, is not sufficient to alter Nup210l and Lhx1 expression. Finally, these two genes are also misregulated in Seh1-deficient neural progenitors, which only show a mild reduction in nuclear pore density. Together these data reveal a shared function of Y-complex nucleoporins in gene regulation during neuroectodermal differentiation, apparently independent of nuclear pore basket integrity.
