KPNA4 also known as importin alpha 4 or karyopherin subunit alpha 4 is a protein involved in nuclear transport mechanisms. It has a molecular weight of approximately 58 kDa. KPNA4 finds expression in various tissues including the brain immune cells and reproductive organs. This protein belongs to the family of karyopherins which mediates the import of proteins into the nucleus by recognizing nuclear localization signals.

Biological function summary

KPNA4 plays a role in transporting proteins into the nucleus as part of the importin complex. This complex forms through the association of KPNA4 with importin beta facilitating the translocation of cargo proteins through the nuclear pore complex. This translocation process is essential for regulating gene expression and cellular functions as proteins must reach the cell nucleus to execute their roles. KPNA4 interacts with various cargo proteins allowing them to partake in nuclear activities essential for cellular activity and response.

Pathways

KPNA4 participates in the nuclear import pathway closely linking with the Ran GTPase cycle. This pathway is important for transporting macromolecules between the cytoplasm and nucleus. KPNA4's action complements the function of the importin beta family where it co-transports with proteins like Ran and importin beta ensuring effective and specific nuclear import of karyophilic proteins. The presence of KPNA4 in these pathways highlights its importance in cellular regulation and response paths.

KPNA4 shows connections to neurodegenerative diseases and certain cancers suggesting its potential role in these conditions. In neurodegenerative diseases its association with proteins involved in intracellular transport could imply a role in pathological processes where nuclear-cytoplasmic trafficking is disrupted. Furthermore KPNA4's interaction with proteins like importin beta in cancer could influence tumor progression through altered nuclear transport impacting gene expression and cell cycle regulation. Recognizing these associations might provide insights for therapeutic targeting or diagnostic markers in related conditions.

Target data

Functions in nuclear protein import as an adapter protein for nuclear receptor KPNB1 (PubMed : 10567565, PubMed : 20818336, PubMed : 28760339, PubMed : 29042532, PubMed : 38512451). Binds specifically and directly to substrates containing either a simple or bipartite NLS motif (PubMed : 20818336, PubMed : 28760339, PubMed : 29042532, PubMed : 38512451). Docking of the importin/substrate complex to the nuclear pore complex (NPC) is mediated by KPNB1 through binding to nucleoporin FxFG repeats and the complex is subsequently translocated through the pore by an energy requiring, Ran-dependent mechanism (PubMed : 20818336, PubMed : 28760339, PubMed : 29042532, PubMed : 38512451). At the nucleoplasmic side of the NPC, Ran binds to importin-beta and the three components separate and importin-alpha and -beta are re-exported from the nucleus to the cytoplasm where GTP hydrolysis releases Ran from importin (PubMed : 20818336, PubMed : 28760339, PubMed : 29042532, PubMed : 38512451). 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 (PubMed : 20818336, PubMed : 28760339, PubMed : 29042532, PubMed : 38512451). Mediates nuclear import of AARS1, MRTFA and RANBP3 (PubMed : 10567565, PubMed : 20818336, PubMed : 28760339, PubMed : 38512451)..
