  Function in Host
Translation initiation regulator which represses repeat-associated non-AUG (RAN) initiated translation probably by acting as acompetitive inhibitor of eukaryotic translation initiation factor 5 (EIF5) function. Enhances histone H4gene transcription but does not seem to bind DNA directly. [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 BZW1 in viral infection, BZW1 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 BZW1 increases SARS-CoV-2 RNA levels compared with control group.
