Protein Information (annotations from UniProt)

Database IDHIV0002032
UniProt IDQ9UKX7
Primary gene name(s)NUP50
Synonym gene name(s)NPAP60L
Protein nameNuclear pore complex protein Nup50
Protein functionComponent of the nuclear pore complex that has a direct role in nuclear protein import. Actively displaces NLSs from importin-alpha, and facilitates disassembly of the importin-alpha:beta-cargo complex and importin recycling. Interacts with multiple transport receptor proteins including CDKN1B. This interaction is required for correct intracellular transport and degradation of CDKN1B. {ECO:0000269|PubMed:20016008}.
Subcellular locationNucleus, nuclear pore complex {ECO:0000269|PubMed:12802065}. Nucleus membrane {ECO:0000250};
Peripheral membrane protein {ECO:0000250};
Nucleoplasmic side {ECO:0000250}. Note=Localizes to the nucleoplasmic fibrils of the nuclear pore complex, By similarity. Dissociates from the NPC structure early during prophase of mitosis. Associates to the newly formed nuclear membrane during telophase. {ECO:0000250}.
