'''Exportins''' (XPO) or '''chromosomal maintenance protein''' mediate the nuclear export of cellular proteins with a leucine-rich export signal (NES) and RNA. XPO is regulated by GTPaseRan. RanGTP bind to XPO forming a ternary complex with the exported protein. The complex diffuses through the nuclear core complex to the cytoplasm and then dissociates. '''XPO-t''' exports tRNA from the nucleus<ref>PMID:17786152</ref>. | '''Exportins''' (XPO) or '''chromosomal maintenance protein''' mediate the nuclear export of cellular proteins with a leucine-rich export signal (NES) and RNA.
