The nuclear pore complex (NPC) mediates bidirectional macromolecular traffic between the nucleus and cytoplasm in eukaryotic cells and is comprised of more than 100 different subunits. Many of the subunits belong to a family called nucleoporins (Nups), which are characterized by the presence of O-linked-N-acetylglucosamine moieties and a distinctive pentapeptide repeat (XFXFG). NupL1 (Nucleoporin-like 1), also designated nucleoporin p58/p45, is a 599 amino acid protein that contains FG repeats and exists as a component of the p62 complex, which includes Nup62, Nup54, and NupL1. The p62 complex localizes near the central gated channel of the nuclear pore complex. Specifically, NupL1 interacts with SRP1-alpha and Importin p97 when they are together, but not with SRP1-alpha protein alone. |
