  Function in Host
Component of the cleavage and polyadenylation specificityfactor (CPSF) complex that play a key role in pre-mRNA 3'-endformation, recognizing the AAUAAA signal sequence and interacting withpoly (A) polymerase and other factors to bring about cleavage andpoly (A) addition. Involved in the histone 3' end pre-mRNA processing. [1-2]

Function of This Protein During Virus Infection
Virus NameSARS-COV-2 Protein Function Anti-viral [3]
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 CPSF2 in viral infection, CPSF2 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 CPSF2 increases SARS-CoV-2 RNA levels compared with control group.
