General description

DBP5 belongs to the family of the DEAD-box helicases that are involved in cellular RNA metabolism from transcription through pre-mRNA splicing, nuclear export, translation initiation to RNA degradation. It localizes within the cytoplasm and at the nuclear rim, where it interacts with components of the nuclear pore complex (NPC). It shuttles between the nucleus and the cytoplasm by using Nup159 as a binding platform.


Anti-DBP5 antibody produced in rabbit is suitable for immunoprecipitation at a working amount of 5-10μL using HEK-293T cell lysate, immunoblotting at a working concentration of 1-2μg/mL using HEK-293T cell lysate and immunofluorescence at a working concentration of 2.5-5μg/mL using paraformaldehyde fixed HEK-293T cells over-expressing human DBP5.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.

Biochem/physiol Actions

DBP5 is required for mRNA export from the nucleus in an ATP-dependent manner. It is also involved in translation termination, where it recognizes stop-codon by controlling eRF1-eRF3 interaction.
