A new family of yeast nuclear pore complex proteins
We have identified a novel family of yeast nuclear pore complex proteins. Three individual members of this family, NUP49, NUP100, and NUP116, have been isolated and then characterized by a combination of molecular genetics and immunolocalization. Employing immunoelectron and immunofluorescence microscopy on yeast cells, we found that the binding of a polyspecific monoclonal antibody recognizing...
متن کاملInheritance of yeast nuclear pore complexes requires the Nsp1p subcomplex
In the yeast Saccharomyces cerevisiae, organelles and macromolecular complexes are delivered from the mother to the emerging daughter during cell division, thereby ensuring progeny viability. Here, we have shown that during mitosis nuclear pore complexes (NPCs) in the mother nucleus are actively delivered through the bud neck and into the daughter cell concomitantly with the nuclear envelope. F...
متن کاملThe Yeast Nuclear Pore Complex
An understanding of how the nuclear pore complex (NPC) mediates nucleocytoplasmic exchange requires a comprehensive inventory of the molecular components of the NPC and a knowledge of how each component contributes to the overall structure of this large molecular translocation machine. Therefore, we have taken a comprehensive approach to classify all components of the yeast NPC (nucleoporins). ...
متن کاملNuclear mRNA export requires specific FG nucleoporins for translocation through the nuclear pore complex
Trafficking of nucleic acids and large proteins through nuclear pore complexes (NPCs) requires interactions with NPC proteins that harbor FG (phenylalanine-glycine) repeat domains. Specialized transport receptors that recognize cargo and bind FG domains facilitate these interactions. Whether different transport receptors utilize preferential FG domains in intact NPCs is not fully resolved. In t...
متن کاملTargeting and function in mRNA export of nuclear pore complex protein Nup153
Nup153 is a large (153 kD) O-linked glyco-protein which is a component of the basket structure located on the nucleoplasmic face of nuclear pore complexes. This protein exhibits a tripartite structure consisting of a zinc finger domain flanked by large (60-70 kD) NH2- and COOH-terminal domains. When full-length human Nup153 is expressed in BHK cells, it accumulates appropriately at the nucleopl...
