Application Abreviews Notes
WB 1/2000 - 1/10000. Detects a band of approximately 141 kDa (predicted molecular weight: 141 kDa).
IP Use at 2-5 µg/mg of lysate.
IHC-P 1/100 - 1/500. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.


  • FunctionUnwinds double-stranded DNA and RNA in a 3' to 5' direction. Alteration of secondary structure may subsequently influence interactions with proteins or other nucleic acids. Functions as a transcriptional activator. Component of the CRD-mediated complex that promotes MYC mRNA stability.
  • Sequence similaritiesBelongs to the DEAD box helicase family. DEAH subfamily.
    Contains 2 DRBM (double-stranded RNA-binding) domains.
    Contains 1 helicase ATP-binding domain.
    Contains 1 helicase C-terminal domain.
  • DomainThe MTAD domain mediates interaction with the RNA polymerase II holoenzyme. The NTD domain is necessary and sufficient for nucleo-cytoplasmic shuttling and interaction with HRMT1L2 and SMN1.
  • Post-translational
    Methylated. HRMT1L2 mediated methylation of undefined Arg residues in the NTD is required for nuclear localization.
    May be phosphorylated by PRKDC/XRCC7. Phosphorylated upon DNA damage, probably by ATM or ATR.
  • Cellular localizationNucleus > nucleolus. Cytoplasm. Localized in cytoplasmic mRNP granules containing untranslated mRNAs. Can shuttle between nucleus and cytoplasm.
