Rabbit anti-Exportin-5 Antibody Affinity Purified

Exportin-5 mediates the nuclear export of proteins bearing a double-stranded RNA binding domain (dsRBD) and double-stranded RNAs (cargos). Exportin-5 in the nucleus binds cooperatively to the RNA and to the GTPase Ran in its active GTP-bound form. Proteins containing dsRBDs can associate with this trimeric complex through the RNA. Docking of this complex to the nuclear pore complex (NPC) is mediated through binding to nucleoporins. Upon transit of a nuclear export complex into the cytoplasm, hydrolysis of Ran-GTP to Ran-GDP (induced by RANBP1 and RANGAP1, respectively) cause disassembly of the complex and release of the cargo from the export receptor. Exportin-5 then returns to the nuclear compartment by diffusion through the nuclear pore complex, to mediate another round of transport [taken from the Universal Protein Resource (UniProt) www.uniprot.org/uniprot/Q9HAV4].
