Target

  • Function

    Ribonuclease III double-stranded (ds) RNA-specific endoribonuclease that is involved in the initial step of microRNA (miRNA) biogenesis. Component of the microprocessor complex that is required to process primary miRNA transcripts (pri-miRNAs) to release precursor miRNA (pre-miRNA) in the nucleus. Within the microprocessor complex, DROSHA cleaves the 3' and 5' strands of a stem-loop in pri-miRNAs (processing center 11 bp from the dsRNA-ssRNA junction) to release hairpin-shaped pre-miRNAs that are subsequently cut by the cytoplasmic DICER to generate mature miRNAs. Involved also in pre-rRNA processing. Cleaves double-strand RNA and does not cleave single-strand RNA. Involved in the formation of GW bodies.
  • Tissue specificity

    Ubiquitous.
  • Sequence similarities

    Contains 1 DRBM (double-stranded RNA-binding) domain.
    Contains 2 RNase III domains.
  • Domain

    The 2 RNase III domains form an intramolecular dimer where the domain 1 cuts the 3'strand while the domain 2 cleaves the 5'strand of pri-miRNAs, independently of each other.
  • Cellular localization

    Nucleus. Nucleus > nucleolus. A fraction is translocated to the nucleolus during the S phase of the cell cycle. Localized in GW bodies (GWBs), also known as P-bodies.

Images

  • Flow Cytometry analysis of Jurkat (human acute T cell leukemia) cells labeling Drosha with purified ab183732 at 1/230 dilution (10ug/ml) (red). Cells were fixed with 4% paraformaldehyde and permeabilised with 90% methanol. A Goat anti rabbit IgG (Alexa Fluor® 488)(1/2000 dilution) was used as the secondary antibody. Rabbit monoclonal IgG (Black) was used as the isotype control, cells without incubation with primary antibody and secondary antibody (Blue) was used as the unlabeled control.

    This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab183732).

  • Immunocytochemistry/Immunofluorescence analysis of Jurkat cells labelling Drosha with ab183732 at 1/500. Cells were fixed with 4% Paraformaldehyde. ab150077, an Alexa Fluor® 488-conjugated goat anti-rabbit IgG (1/1000) was used as the secondary antibody.

    Control: PBS only.
    Nuclear counter stain: DAPI.

    This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab183732).

  • This IHC data was generated using the same anti-Drosha antibody clone, EPR12794, in a different buffer formulation (cat# ab183732).

    Immunohistochemical analysis of paraffin-embedded Human lung adenocarcinoma tissue labeling Drosha with ab183732 at 1/100 dilution followed by prediluted HRP Polymer for Rabbit IgG. Counter stained with Hematoxylin.
