  Function in Host
Actin-binding protein that is involved in actin cytoskeletonassembly and reorganization. Acts asan actin nucleation factor and promotes assembly of actin filamentstogether with SPIRE1 and SPIRE2. Involved in intracellular vesicle transport along actin fibers, providing a novel link between actin cytoskeleton dynamics andintracellular transport. Required for asymmetricspindle positioning, asymmetric oocyte division and polar bodyextrusion during female germ cell meiosis. Plays a rolein responses to DNA damage, cellular stress and hypoxia by protectingCDKN1A against degradation, and thereby plays a role in stress-inducedcell cycle arrest. Also acts in the nucleus: togetherwith SPIRE1 and SPIRE2, promotes assembly of nuclear actin filaments inresponse to DNA damage in order to facilitate movement of chromatin andrepair factors after DNA damage. Protects cellsagainst apoptosis by protecting CDKN1A against degradation. [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 FMN2 in viral infection, FMN2 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 FMN2 increases SARS-CoV-2 RNA levels compared with control group.
