XPO1

This cell-cycle-regulated gene encodes a protein that mediates leucine-rich nuclear export signal (NES)-dependent protein transport. The protein specifically inhibits the nuclear export of Rev and U snRNAs. It is involved in the control of several cellular processes by controlling the localization of cyclin B, MPAK, and MAPKAP kinase 2. This protein also regulates NFAT and AP-1.

Interaction

Found in a U snRNA export complex with PHAX/RNUXA, NCBP1/CBP80, NCBP2/CBP20, RAN, XPO1 and m7G-capped RNA (By similarity). Component of a nuclear export receptor complex composed of KPNB1, RAN, SNUPN and XPO1. Found in a trimeric export complex with SNUPN, RAN and XPO1. Found in a nuclear export complex with RANBP3 and RAN. Found in a 60S ribosomal subunit export complex with NMD3, RAN, XPO1. Interacts with DDX3X, NMD3, NUP42, NUP88, NUP214, RANBP3 and TERT. Interacts with NEMF (via its N-terminus). Interacts with the monomeric form of BIRC5/survivin deacetylated at 'Lys-129'. Interacts with DTNBP1 and SERTAD2; the interactions translocate DTNBP1 and SERTAD2 out of the nucleus. Interacts with ATF2. Interacts with SLC35G1 and STIM1. Interacts with DCAF8. Interacts with CPEB3 (PubMed:22730302). Interacts with HAX1 (PubMed:23164465). Interacts with BOK; translocates to the cytoplasm (PubMed:16302269). Interacts with HSP90AB1 (PubMed:22022502). (Microbial infection) Interacts with HIV-1 Rev. (Microbial infection) Interacts with HTLV-1 Rex. (Microbial infection) Interacts with influenza A nucleoprotein. (Microbial infection) Interacts with Epstein-Barr virus protein BMLF1. (Microbial infection) Part of a tetrameric complex composed of CRM1, importin alpha/beta dimer and the Venezuelan equine encephalitis virus (VEEV) capsid; this complex blocks the receptor-mediated transport through the nuclear pore. (Microbial infection) Interacts with SARS-CoV virus protein ORF9b; this interaction mediates protein ORF9b export out of the nucleus.
