Function of This Protein During Virus Infection
Virus Name	SARS-COV-2	Protein Function	Anti-viral	[2]
Infected Tissue	Lung	Infection Time	7-9 Days
Infected Cell	Calu-3 Cells (Human epithelial cell line)	Cellosaurus ID	CVCL_0609
Method Description	To detect the role of host protein AHCY in viral infection, AHCY 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.
Results	It is reported that knockout of AHCY increases SARS-CoV-2 RNA levels compared with control group.
