General Comments
Exportin 1 (XPO1) is a major nuclear-cytoplasmic exporter, that in eukaryotes regulates transfer of ~220 endogenous cargo proteins that contain a leucine-rich nuclear export signal (NES). It also binds to and exports HIV-1 Rev and HTLV-1 Rex proteins. Exportin 1 affinity for cargo proteins is regulated by binding of Ran-GTP in the nucleus, and Ran-GAP-mediated Ran-GTP hydrolysis releases the cargo proteins in the cytoplasm. Exportin 1 cargo proteins include tumour suppressor proteins (TSPs), apoptosis inducers and cell cycle regulators. A number of haematologic malignancies and solid tumours have been discovered to be dependent on Exportin 1-mediated nuclear export (particularly export of TSPs) for their survival. In light of this evidence, exportin 1 is being exploited as an oncology drug target [1,3,5,7]. Selinexor (KPT-330) and eltanexor (KPT-8602) are orally bioavailable and selective exportin 1 inhibitors that are in clinical development as novel chemotherapeutics for haematological and solid cancers.
