Summary
IPO8 (importin 8, HGNC:9853) is a protein-coding gene on chromosome 12p11.21, encoding Importin-8 (O15397). Involved in nuclear protein import, either by acting as autonomous nuclear transport receptor or as an adapter-like protein in association with the importin-beta subunit KPNB1.
The importin-alpha/beta complex and the GTPase Ran mediate nuclear import of proteins with a classical nuclear localization signal. The protein encoded by this gene is a member of a class of approximately 20 potential Ran targets that share a sequence motif related to the Ran-binding site of importin-beta. This protein binds to the nuclear pore complex and, along with RanGTP and RANBP1, inhibits the GAP stimulation of the Ran GTPase. Alternatively spliced transcript variants encoding different isoforms have been found for this gene.

- Our studies also suggest that nuclear entry is important for the prooncogenic activity of eIF4E, at least in this context. These findings position nuclear trafficking of eIF4E as a critical step in its regulation and position the importin 8-eIF4E complex as a novel therapeutic target. (PMID:27114554)

Function. Involved in nuclear protein import, either by acting as autonomous nuclear transport receptor or as an adapter-like protein in association with the importin-beta subunit KPNB1. Acting autonomously, may serve as receptor for nuclear localization signals (NLS) and promote translocation of import substrates through the nuclear pore complex (NPC) by an energy requiring, Ran-dependent mechanism. At the nucleoplasmic side of the NPC, Ran binds to importin, the importin/substrate complex dissociates and importin is re-exported from the nucleus to the cytoplasm where GTP hydrolysis releases Ran. The directionality of nuclear import is thought to be conferred by an asymmetric distribution of the GTP- and GDP-bound forms of Ran between the cytoplasm and nucleus. In vitro mediates the nuclear import of the signal recognition particle protein SRP19. May also be involved in cytoplasm-to-nucleus shuttling of a broad spectrum of other cargos, including Argonaute-microRNAs complexes, the JUN protein, RELA/NF-kappa-B p65 subunit, the translation initiation factor EIF4E and a set of receptor-activated mothers against decapentaplegic homolog (SMAD) transcription factors that play a critical role downstream of the large family of transforming growth factor beta and bone morphogenetic protein (BMP) cytokines.
Subunit / interactions. Forms a heterodimer with KPNB1. Interacts with SRP19. Interacts with RPL23A. Binds directly to nuclear pore complexes. Interacts with LRPPRC; the interaction occurs when LRPPRC is in its RNA-free form and promotes import of LRPPRC to the nucleus to allow for EIF4E-mediated export of mRNAS from the nucleus to the cytoplasm.
Subcellular location. Cytoplasm. Nucleus.
Disease relevance. VISS syndrome (VISS) [MIM:619472] An autosomal recessive disease characterized by early-onset thoracic aortic aneurysm, aneurysm and tortuosity of other arteries, motor developmental delay, connective tissue findings such as joint hypermobility, skin laxity and hernias, and craniofacial dysmorphic features. Immune dysregulation has been reported in some patients. The disease is caused by variants affecting the gene represented in this entry.
Similarity. Belongs to the importin beta family.

Enriched among interaction partners
Reactome pathways and GO biological processes over-represented among this gene’s 207 IntAct physical interaction partners (hypergeometric vs the genome-wide background, BH-FDR, gene-set size 15–500, ranked by fold). A functional readout of the neighbourhood — distinct from this gene’s own memberships above, and biased toward well-studied / hub proteins, so read it as themes rather than proof.
