Eukaryotic ribosome biogenesis requires nuclear import and hierarchical incorporation of ∼80 ribosomal proteins (RPs) into the ribosomal RNA core. In contrast to prokaryotes, many eukaryotic RPs possess long extensions that interdigitate in the mature ribosome. RpL4 is a prime example, with an ∼80-residue-long surface extension of unknown function. Here, we identify assembly chaperone Acl4 that initially...

Many cellular proteins perform their roles within macromolecular assemblies. Hence, an understanding of how these multiprotein complexes form is a fundamental question in cell biology. We developed a translation-controlled pulse-chase system that allows time-resolved isolation of newly forming multiprotein complexes in chemical quantities suitable for biochemical and cell biological analysis. The...

Nic96 is a conserved nucleoporin that recruits the Nsp1-Nup49-Nup57 complex, a module with Phe-Gly (FG) repeats, to the central transport channel of the nuclear pore complex (NPC). Nic96 binds the Nsp1 complex via its N domain and assembles into the NPC framework via its central and C domain. Here, we report the crystal structure of a large structural nucleoporin, Nic96 without its N domain (Nic96ΔN)...
