  Function in Host
Binds ATP, opioids and phosphatidylethanolamine. Has loweraffinity for phosphatidylinositol and phosphatidylcholine. Serineprotease inhibitor which inhibits thrombin, neuropsin and chymotrypsinbut not trypsin, tissue type plasminogen activator and elastase. Inhibits the kinase activity of RAF1 by inhibiting itsactivation and by dissociating the RAF1/MEK complex and acting as acompetitive inhibitor of MEK phosphorylation. [1]

Function of This Protein During Virus Infection
Virus NameSARS-COV-2 Protein Function Pro-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 PEBP1 in viral infection, PEBP1 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 PEBP1 leads to the decreased SARS-CoV-2 RNA levels compared with control group.
