NUP53 encodes a recently identified nuclear pore protein, described in (1). 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 11, 12, 13, 14). The structure of the vertebrate NPC has been studied extensively; recent reviews include 15, 16, 17, and 18. The yeast NPC shares several features with the vertebrate NPC, despite being smaller and less elaborate (19, 20). Many yeast nuclear pore proteins, or nucleoporins, have been identified by a variety of genetic approaches (reviewed in 11, 12, 21, 22, 23). Nup53p forms a complex with two other nucleoporins, Nup170p and Asm4p. The complex is found on both the nuclear and cytoplasmic faces of the NPC, and associates with Pse1p, a member of a protein family implicated in nuclear protein import, via direct interaction between Nup53p and Pse1p. Nup53p is structurally similar to Asm4p, and similar proteins sequences are found in several eukaryotes including human and other multicellular species. Nup53p is not essential; deletion of NUP53 and ASM4 causes slow growth and altered subcellular distribution of Pse1p. In a nup53 pse1 double mutant, NLS-containing proteins are mislocalized to the cytoplasm.
