  Function in Host
Required for RNA-mediated gene silencing (RNAi). Binds toshort RNAs such as microRNAs (miRNAs) or short interfering RNAs (siRNAs), and represses the translation of mRNAs which arecomplementary to them. Lacks endonuclease activity and does not appearto cleave target mRNAs. Also required for transcriptional genesilencing (TGS) of promoter regions which are complementary to boundshort antigene RNAs (agRNAs). [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 AGO1 in viral infection, AGO1 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 AGO1 increases SARS-CoV-2 RNA levels compared with control group.
