Target

  • Function

    Can unwind double-stranded RNA (helicase) and can fold or introduce a secondary structure to a single-stranded RNA (foldase). Functions as cofactor for JUN-activated transcription. Involved in rRNA processing.
  • Sequence similarities

    Belongs to the DEAD box helicase family. DDX21/DDX50 subfamily.
    Contains 1 helicase ATP-binding domain.
    Contains 1 helicase C-terminal domain.
  • Domain

    The two enzymatic activities reside in two separate domains, the helicase in the N-terminus and the foldase in the C-terminus.
    The 3 X 5 AA repeats seem to be critical for the RNA folding activity.
  • Cellular localization

    Nucleus > nucleolus.

  • Immunohistochemical analysis of paraffin-embedded Human infiltrating duct carcinoma of breast tissue, staining DDX21 with ab182156 at 1/100 dilution. Hematoxylin was used as a counterstain.

    Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.

  • Immunofluorescence analysis of HeLa cells, staining DDX21 (red) with ab182156 at 1/100 dilution. An Alexa Fluor®555 goat anti rabbit IgG was used as a secondary antibody. Cells were fixed with -20℃ Acetone. Nuclei were counterstained with DAPI (blue).

  • Immunofluorescence analysis of HepG2 cells, staining DDX21 (green) with ab182156 at 1/100 dilution. An Alexa Fluor®488 goat anti rabbit IgG was used as a secondary antibody. Cells were fixed in 4% paraformaldehyde. Nuclei were counterstained with DAPI (blue).
