  Function in Host
Possesses 5'->3' exoribonuclease activity. May promote the termination of transcription by RNA polymerase II. During transcription termination, cleavage at the polyadenylation siteliberates a 5' fragment which is subsequently processed to form themature mRNA and a 3' fragment which remains attached to the elongatingpolymerase. The processive degradation of this 3' fragment by thisprotein may promote termination of transcription. Binds to RNApolymerase II (RNAp II) transcription termination R-loops formed by G-rich pause sites. [1-3]

Function of This Protein During Virus Infection
Virus NameSARS-COV-2 Protein Function Anti-viral [4]
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 XRN2 in viral infection, XRN2 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 XRN2 increases SARS-CoV-2 RNA levels compared with control group.
