POM152 encodes a nuclear pore protein (1, 7). 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 7, 8, 9, 10). The structure of the vertebrate NPC has been studied extensively; recent reviews include 11, 12, 13, and 14. The yeast NPC shares several features with the vertebrate NPC, despite being smaller and less elaborate (15, 16). Many yeast nuclear pore proteins, or nucleoporins, have been identified by a variety of genetic approaches (reviewed in 7, 8, 17, 18, 19). Pom152p is an integral membrane protein (1), and is one of the most abundant yeast nucleoporins (20). Pom152p interacts physically with other abundant yeast nucleoporins, Nic96p, Nup157p, Nup170p, and Nup188p (21, 7). These abundant nucleoporins may form the structural core of the NPC (7). POM152 is not essential, but overproduction of Pom152p inhibits cell growth (1). pom152 mutations are also synthetically lethal with mutations in several nucleoporin genes (20, 21, 7, 22). Analysis of the domain structure and membrane topology of Pom152p reveals that different domains may have different functions, and show different genetic interactions with other nucleoporin genes (22). Deletion of POM152 suppresses a spindle pole body duplication defect caused by a mutation in NDC1, which encodes a shared component of the nuclear pore and the spindle pole body (23).
