  Function in Host
Plays a role in RNA-mediated gene silencing by both micro-RNAs (miRNAs) and short interfering RNAs (siRNAs). Required for miRNA-dependent translational repression and siRNA-dependent endonucleolyticcleavage of complementary mRNAs by argonaute family proteins. As scaffolding protein associates with argonaute proteins bound topartially complementary mRNAs and simultaneously can recruit CCR4-NOTand PAN deadenylase complexes. [1-5]

Function of This Protein During Virus Infection
Virus NameSARS-COV-2 Protein Function Anti-viral [6]
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 TNRC6B in viral infection, TNRC6B protein knockdown 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 TNRC6B increases SARS-CoV-2 RNA levels compared with control group.
