  • Function
    Putative catalytic component of the RNA exosome complex which has 3'->5' exoribonuclease activity and participates in a multitude of cellular RNA processing and degradation events. In the nucleus, the RNA exosome complex is involved in proper maturation of stable RNA species such as rRNA, snRNA and snoRNA, in the elimination of RNA processing by-products and non-coding 'pervasive' transcripts, such as antisense RNA species and promoter-upstream transcripts (PROMPTs), and of mRNAs with processing defects, thereby limiting or excluding their export to the cytoplasm. The RNA exosome may be involved in Ig class switch recombination (CSR) and/or Ig variable region somatic hypermutation (SHM) by targeting AICDA deamination activity to transcribed dsDNA substrates. In the cytoplasm, the RNA exosome complex is involved in general mRNA turnover and specifically degrades inherently unstable mRNAs containing AU-rich elements (AREs) within their 3' untranslated regions, and in RNA surveillance pathways, preventing translation of aberrant mRNAs. It seems to be involved in degradation of histone mRNA. EXOSC10 has 3'-5' exonuclease activity (By similarity). EXOSC10 is required for nucleolar localization of C1D and probably mediates the association of SKIV2L2, C1D and MPP6 wth the RNA exosome involved in the maturation of 5.8S rRNA.
  • Sequence similarities
    Contains 1 3'-5' exonuclease domain.
    Contains 1 HRDC domain.
  • Cellular localization
    Cytoplasm. Nucleus, nucleolus. Nucleus. Strongly enriched in the nucleolus and a small amount has been found in cytoplasm supporting the existence of a nucleolar RNA exosome complex form.

  • ab50558 staining EXOSC10 in murine NIH3T3 cells by Immunocytochemistry/ Immunofluorescence.
    Cells were fixed in 3.7% formaldehyde and permeabilized overnight in 70% ethanol at -20°C and then 30 minutes with 0.5% Triton. Samples were then blocked and incubated with ab50558 at a 1/435 dilution for 30 minutes at 20°C. The secondary used was a goat anti-rabbit polyclonal conjugated to Alex Fluor 594, used at a 1/1000 dilution. Nuclei stained with DAPI.
