Function of This Protein During Virus Infection
Virus NameSARS-COV-2 Protein Function Anti-viral [3]
Infected TissueLung Infection Time24 h; 48 h
Infected CellCalu-3 cells (Human lung cancer cell line) Cellosaurus IDCVCL_0609 
Method DescriptionTo detect the role of host protein EIF4H in viral infection, EIF4H protein knockout Calu-3 cells were infected with SARS-COV-2 for 24 - 48 h , and the effects on infection was detected through qRT-PCR.
ResultsIt is reported that Knockdown of EIF4H increases SARS-CoV-2 RNA levels compared with control group.
