General description

Probable ATP-dependent RNA helicase DDX6 also known as DEAD box protein 6 or Oncogene RCK/p54, is a conserved member of the DEAD-box RNA helicase family. DDX6 plays a central role in P-body assembly in mammals and its depletion prevents P-body assembly leading to P-bodies disappearance.1 DDX6 coordinates RNA and ATP helicase binding activities and binds along the mRNA. DDX6 sequence specific binding at mRNA 5′ end, activates recruitment of the decapping complex, thus coupling translational repression and mRNA degradation.1-2partial human DDX6 recombinant protein 

Specificity

Monoclonal Anti-DDX6 antibody specifically recognizes DDX6 from human, mouse, monkey, canine and bovine origin.

Immunogen

partial human DDX6 recombinant protein

Application

The antibody may be used in various immunochemical techniques including Immunoblotting (~54 kDa) and Immunofluorescence. Detection of the DDX6 band by Immunoblotting is specifically inhibited by the immunogen.

Biochem/physiol Actions

DDX6 is considered to be a P-bodies marker due to its mediating role between translational repression and P-bodies formation and toits interaction with Ago2 and the RISC complex that also mediates translational silencing by miRNAs.1-4  Viruses like Hepatitis C virus (HCV) or West Nile virus (WNV) utilize the host cell DDX6 to promote virus infection by recruiting it to the viral replication sites where it is involved in stabilization of the viral genome and the shift between translation and replication.2,5-6DDX6 was reported to be overexpressed in colorectal adenocarcinomas, gastric cancer and in most malignant cell lines.7-9 It was suggested that DDX6 acted as an upstream cancerous enhancer through RNA-binding of HER2 and FGFR2 mRNAs that positively regulates post-transcriptional processes in cancer cells.7

Physical form

Supplied as a solution in 0.01 M phosphate buffered saline pH 7.4, containing 15 mM sodium azide as a preservative.

Storage and Stability

For continuous use, store at 2-8°C for up to one month. For extended storage, freeze in working aliquots. Repeated freezing and thawing is not recommended. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use. Working dilution samples should be discarded if not used within 12 hours.
