  Function in Host
Putative catalytic component of the RNA exosome complex whichhas 3'->5' exoribonuclease activity and participates in a multitude ofcellular RNA processing and degradation events. In the nucleus, the RNAexosome complex is involved in proper maturation of stable RNA speciessuch as rRNA, snRNA and snoRNA, in the elimination of RNA processingby-products and non-coding 'pervasive' transcripts, such as antisenseRNA species and promoter-upstream transcripts (PROMPTs), and of mRNAswith processing defects, thereby limiting or excluding their export tothe cytoplasm. The RNA exosome may be involved in Ig class switchrecombination (CSR) and/or Ig variable region somatic hypermutation (SHM) by targeting AICDA deamination activity to transcribed dsDNAsubstrates. In the cytoplasm, the RNA exosome complex is involved ingeneral mRNA turnover and specifically degrades inherently unstablemRNAs containing AU-rich elements (AREs) within their 3' untranslatedregions, and in RNA surveillance pathways, preventing translation ofaberrant mRNAs. It seems to be involved in degradation of histone mRNA. EXOSC10 has 3'-5' exonuclease activity. EXOSC10 isrequired for nucleolar localization of C1D and probably mediates theassociation of MTREX, C1D and MPHOSPH6 with the RNA exosome involved inthe maturation of 5. 8S rRNA.

Function of This Protein During Virus Infection
Virus NameSARS-COV-2 Protein Function Pro-viral [1]
Infected TissueLung Infection Time7-9 Days
Infected CellCalu-3 Cells (Human epithelial cell line) Cellosaurus IDCVCL_0609 
Method DescriptionTo detect the role of host protein EXOSC10 in viral infection, EXOSC10 protein knockout Calu-3 Cells were infected with SARS-COV-2 for 7 - 9 Days , and the effects on infection was detected through CRISPR-based genome-wide gene-knockout screen.
ResultsIt is reported that knockout of EXOSC10 leads to the decreased SARS-CoV-2 RNA levels compared with control group.
