NUP84/YDL116W Summary Help

Standard Name NUP84 1
Systematic Name YDL116W
Feature Type ORF, Verified
Description Subunit of the Nup84p subcomplex of the nuclear pore complex (NPC); contributes to nucleocytoplasmic transport and NPC biogenesis; also plays roles in several processes that may require localization of genes or chromosomes at the nuclear periphery, including double-strand break repair, transcription and chromatin silencing; homologous to human NUP107 (2, 3, 4, 5, 6, 7, 8, 9 and see Summary Paragraph)

NUP84 encodes a nuclear pore protein homologous to the rat nucleoporin Nup107p (1, 10). Transport of macromolecules between the nucleus and the cytoplasm of eukaryotic cells occurs through the nuclear pore complex (NPC), a large macromolecular complex that spans the nuclear envelope (reviewed in 10, 11, 12, 13). The structure of the vertebrate NPC has been studied extensively; recent reviews include 14, 15, 16, and 17. The yeast NPC shares several features with the vertebrate NPC, despite being smaller and less elaborate (18, 19). Many yeast nuclear pore proteins, or nucleoporins, have been identified by a variety of genetic approaches (reviewed in 10, 11, 20, 21, 22). NUP84 was identified using an allele that is synthetically lethal with a temperature sensitive allele of NSP1 (1). Nup84p is part of subcomplex within the NPC that also includes Sec13p, Seh1p, Nup85p, and Nup120p (1, 10). The nup84 null mutant is viable but temperature sensitive. At the restrictive temperature the mutant shows altered distribution of NPCs and accumulates poly(A) RNA in the nucleus, while nuclear proteins are correctly localized. The seh1 nup84 double null is inviable (1). NUP84 also shows genetic interactions with a sporulation factor, SPO7, and a novel gene, NEM1, which both appear to be involved in nuclear envelope biogenesis (23).
