WebThe dominant nucleotide binding state of Ran depends on whether it is located in the nucleus (RanGTP) or the cytoplasm (RanGDP). Nuclear export. Nuclear export roughly reverses the import process; in the nucleus, the exportin binds the cargo and Ran-GTP and diffuses through the pore to the cytoplasm, where the complex dissociates. WebAfter export to the cytoplasm, GTP hydrolysis by Ran-GAP and RanBP1/2 allows separation of the exportin/cargo/Ran-GTP complex. Ran is then recycled back to the …
