  • 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 anti-sense 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. DIS3 has both 3'-5' exonuclease and endonuclease activities.
  • Tissue specificity

    Widely expressed.
  • Sequence similarities

    Belongs to the RNR ribonuclease family.
    Contains 1 PINc domain.
  • Cellular localization

    Cytoplasm. Nucleus > nucleolus. Nucleus > nucleoplasm. Nucleus. Predominantly located in the nucleus. According to PubMed:12429849, found in the nucleolus and according to PubMed:20531386, excluded from nucleolus supporting the existence of a nucleolar RNA exosome complex devoid of DIS3.

Customer reviews and Q&As


Thank you for your enquiry.

I can confirm that this antibody has been tested on endogenous samples in WB and ICC-IF in the two publications provided on the datasheet:

Pfeiffer JR et al. CARHSP1 is required for effective tumor necrosis factor alpha mRNA stabilization and localizes to processing bodies and exosomes. Mol Cell Biol 31:277-86 (2011). ICC/IF; Mouse.http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?cmd=Retrieve&db=PubMed&list_uids=21078874&dopt=Abstract

I hope this will be helpful and provide some reassurance. I would also like to confirm that this antibody is covered by our 6 month guarantee in the tested applications and species listed on the datasheet (WB, ICC-IF in mouse and human samples) .

I hope this will be useful. If you have any further questions, please do not hesitate to contact me.
