  Function in Host
Plays a crucial role in regulating the dynamics and assemblyof the actin cytoskeleton. Binds to activated CDC42 but does notstimulate its GTPase activity. It associates with calmodulin. Couldserve as an assembly scaffold for the organization of a multimolecularcomplex that would interface incoming signals to the reorganization ofthe actin cytoskeleton at the plasma membrane. May promote neuriteoutgrowth. May play a possible role in cell cycleregulation by contributing to cell cycle progression after DNAreplication arrest. [1-2]

Function of This Protein During Virus Infection
Virus NameSARS-COV-2 Protein Function Pro-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 IQGAP1 in viral infection, IQGAP1 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 IQGAP1 leads to the decreased SARS-CoV-2 RNA levels compared with control group.
