  Function in Host
Binds to WASL/N-WASP and suppresses its translocation fromthe nucleus to the cytoplasm, thereby inhibiting its cytoplasmicfunction. Plays a role in the regulation of cellmorphology and cytoskeletal organization. Required in the control ofcell shape and migration. May play a role in cytokinesis. May beinvolved in pre-mRNA splicing. [1]

Function of This Protein During Virus Infection
Virus NameSARS-COV-2 Protein Function Anti-viral [2]
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 PRPF40A in viral infection, PRPF40A 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 PRPF40A increases SARS-CoV-2 RNA levels compared with control group.
