DESCRIPTION

Also known as NU153_RAT, Nup153. Component of the nuclear pore complex (NPC), a complex required for the trafficking across the nuclear envelope. Functions as a scaffolding element in the nuclear phase of the NPC essential for normal nucleocytoplasmic transport of proteins and mRNAs. Involved in the quality control and retention of unspliced mRNAs in the nucleus; in association with TPR, regulates the nuclear export of unspliced mRNA species bearing constitutive transport element (CTE) in a NXF1- and KHDRBS1-independent manner. Mediates TPR anchoring to the nuclear membrane at NPC (By similarity). The repeat-containing domain may be involved in anchoring other components of the NPC to the pore membrane. Possible DNA-binding subunit of the nuclear pore complex (NPC) (By similarity). Part of the nuclear pore complex (NPC). Interacts with TPR (via coiled coil region); the interaction is direct and provides a link between the core structure and the TPR-containing nuclear basket of the nuclear pore complex (NPC). Interacts with HIKESHI, SENP2 and XPO5 (By similarity). Interacts with RAN; the interaction occurs in a GTP- and GDP-independent manner. Interacts with MCM3AP; this interaction is required for MCM3AP localization at the nuclear pore complex (By similarity).
