  Function in Host
Promotes orthogonal branching of actin filaments and linksactin filaments to membrane glycoproteins. Anchors varioustransmembrane proteins to the actin cytoskeleton and serves as ascaffold for a wide range of cytoplasmic signaling proteins. Interaction with FLNB may allow neuroblast migration from theventricular zone into the cortical plate. Tethers cell surface-localized furin, modulates its rate of internalization and directs itsintracellular trafficking. Involved in ciliogenesis. Plays a role in cell-cell contacts and adherens junctions during thedevelopment of blood vessels, heart and brain organs. Plays a role inplatelets morphology through interaction with SYK that regulatesITAM- and ITAM-like-containing receptor signaling, resulting in byplatelet cytoskeleton organization maintenance. Duringthe axon guidance process, required for growth cone collapse induced bySEMA3A-mediated stimulation of neurons. [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 FLNA in viral infection, FLNA 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 FLNA increases SARS-CoV-2 RNA levels compared with control group.
