CC -!- FUNCTION: Mediates the nuclear export of aminoacylated tRNAs. In the
CC nucleus binds to tRNA and to the GTPase Ran in its active GTP-bound
CC form. Docking of this trimeric complex to the nuclear pore complex
CC (NPC) is mediated through binding to nucleoporins. Upon transit of a
CC nuclear export complex into the cytoplasm, disassembling of the complex
CC and hydrolysis of Ran-GTP to Ran-GDP (induced by RANBP1 and RANGAP1,
CC respectively) cause release of the tRNA from the export receptor. XPOT
CC then return to the nuclear compartment and mediate another round of
CC transport. The directionality of nuclear export is thought to be
CC conferred by an asymmetric distribution of the GTP- and GDP-bound forms
CC of Ran between the cytoplasm and nucleus (By similarity).
CC {ECO:0000250}.
CC -!- SUBUNIT: Found in a complex with XPOT, Ran and tRNA. Probably found in
CC a complex with nucleoporins. Interacts with Ran and tRNA in a GTP-
CC dependent manner (By similarity). {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250}. Cytoplasm {ECO:0000250}.
CC Note=Nuclear, once bound to tRNA and Ran the complex translocates to
CC the cytoplasm. Shuttles between the nucleus and the cytoplasm (By
CC similarity). {ECO:0000250}.
