  Function in Host
Component of the CYFIP1-EIF4E-FMR1 complex which binds to themRNA cap and mediates translational repression. In the CYFIP1-EIF4E-FMR1 complex this subunit is an adapter between EIF4E and FMR1. Promotes the translation repression activity of FMR1 in brain probablyby mediating its association with EIF4E and mRNA. Regulates formation of membrane ruffles and lamellipodia. Plays a rolein axon outgrowth. Binds to F-actin but not to RNA. Part of the WAVEcomplex that regulates actin filament reorganization via itsinteraction with the Arp2/3 complex. Actin remodeling activity isregulated by RAC1. Regulator of epithelial morphogenesis. As componentof the WAVE1 complex, required for BDNF-NTRK2 endocytic trafficking andsignaling from early endosomes. May act as an invasionsuppressor in cancers. [1-4]

Function of This Protein During Virus Infection
Virus NameSARS-COV-2 Protein Function Anti-viral [5]
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 CYFIP1 in viral infection, CYFIP1 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 CYFIP1 increases SARS-CoV-2 RNA levels compared with control group.
