Function of This Protein During Virus Infection
Virus NameSARS-COV-2 Protein Function Anti-viral [3]
Infected TissueColon Infection Time48 h
Infected CellCaco-2 cells (Human colorectal adenocarcinoma cell) Cellosaurus IDCVCL_0025 
Method DescriptionTo detect the role of host protein GGCT in viral infection, GGCT protein knockout Caco-2 cells were infected with SARS-COV-2 for 48 h , and the effects on infection was detected through qPCR.
ResultsIt is reported that Knockdown of GGCT leads to the Increase the vRNA levels compared with control group.
