NUP116 encodes a nuclear pore protein (1, 13). 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 13, 14, 15, 16). The structure of the vertebrate NPC has been studied extensively; recent reviews include 17, 18, 19, and 20. The yeast NPC shares several features with the vertebrate NPC, despite being smaller and less elaborate (21, 22). Many yeast nuclear pore proteins, or nucleoporins, have been identified by a variety of genetic approaches (reviewed in 13, 14, 23, 24, 25). NUP116 is not essential, but the null mutant is temperature sensitive, and nup116 mutants have defects in nuclear RNA export and nuclear tRNA export and altered nuclear envelope morphology (26, 2, 13, 27). Nup116p is one of a group of nucleoporins that contain multiple repeats of the amino acids GLFG (1, 28, 13). Nup100p and Nup116p are similar over their entire lengths, and may have arisen by gene duplication (1, 29, 13). Deletion of the GLFG repeats from Nup116p causes a defect in nuclear protein import (4, 13). Nup116p interacts with two nuclear transport factors, Kap95p (4) and Pse1p (30). The interaction with Kap95p involves the GLFG repeats of Nup116p (4). Nup116p is stoichiometrically bound to the mRNA transport factor Gle2p, forming a stable complex, via a short sequence (the GLEBS) also found in nucleoporins from rat and Xenopus (31). A related nucleoporin, Nup98, has been identified in vertebrates (13, 32, 33).
