NUP145/YGL092W Summary Help

Standard Name NUP145 1, 2
Systematic Name YGL092W
Alias RAT10
Feature Type ORF, Verified
Description Essential protein with distinct roles in two nuclear pore subcomplexes; catalyzes its own proteolytic cleavage in vivo to generate a C-terminal fragment that is a structural component of the Nup84p subcomplex (with roles in NPC biogenesis and localization of genes to the nuclear periphery), and an N-terminal fragment that is one of several FG-nucleoporins within the NPC central core directly responsible for nucleocytoplasmic transport; homologous to human NUP98 (3, 4, 5, 6, 7, 8, 9, 10 and see Summary Paragraph)

NUP145 encodes an essential nuclear pore protein (12). 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 12, 13, 14, 15). The structure of the vertebrate NPC has been studied extensively; recent reviews include 16, 17, 18, and 19. The yeast NPC shares several features with the vertebrate NPC, despite being smaller and less elaborate (20, 21). Many yeast nuclear pore proteins, or nucleoporins, have been identified by a variety of genetic approaches (reviewed in 12, 13, 22, 23, 24). The N- and C-terminal domains of Nup145p are functionally distinct (25, 26, 4) and are cleaved in vivo (26, 4), though the cleavage is not essential for Nup145p function (26). The N-terminal half of Nup145p contains multiple repeats of the amino acids GLFG (27, 12) and is similar to Nup100p and Nup116p (1, 12). The C-terminal half assembles into the NPC subcomplex containing Nup84p and several other nucleoporins (4, 28, 12). Mutations in NUP145 cause defects in nuclear protein import and nuclear RNA export (2, 29, 12, 26, 25). nup145 mutations are also synthetically lethal with mutations in several other nucleoporin genes (12). A related nucleoporin, Nup98, has been identified in vertebrates (12).
