Function of This Protein During Virus Infection
Virus NameSARS-COV-2 Protein Function Anti-viral [2]
Infected TissueLung Infection Time24 h
Infected CellA549 Cells (Adenocarcinomic Human alveolar basal epithelial cells) Cellosaurus IDCVCL_H249 
Method DescriptionTo detect the role of host protein MAP4 in viral infection, MAP4 protein knockdown A549 Cells were infected with SARS-COV-2 for 24 h , and the effects on infection was detected through qRT-PCR.
ResultsIt is reported that Knockdown of MAP4 increases the percent of infected cells 150% compared with control group.
