The DEAD-box RNA helicase Dbp5 is an essential and conserved mRNA export factor which functions in the ATP dependent remodeling of RNA/protein complexes. As such it displaces mRNA bound proteins at the cytoplasmic site of the nuclear pore complex. For the regulation of its RNA-dependent ATPase activity during late steps of nuclear transport, Dbp5 requires the nucleoporin Nup159 and its cofactors Gle1 and IP6. In addition to its role in mRNA export, a second important function of Dbp5 was identified in translation termination, where it acts together with eRF1 once the translation machinery has reached the stop codon. Similar to mRNA export, this function also requires Gle1-IP6, however, the counterpart of Nup159 is still missing. Potential other functions of the nucleo-cytoplasmic protein Dbp5 are discussed as well as its substrate specificity and details in its regulatory cycle that are based on recent biochemical and structural characterization. This article is part of a Special Issue entitled: The Biology of RNA helicases - Modulation for life.
