  Function in Host
Cell adhesion molecule which is required for leukocytetransendothelial migration (TEM) under most inflammatory conditions. Tyr-690 plays a critical role inTEM and is required for efficient trafficking of PECAM1 to and from thelateral border recycling compartment (LBRC) and is also essential forthe LBRC membrane to be targeted around migrating leukocytes. Trans-homophilic interaction may play a role inendothelial cell-cell adhesion via cell junctions. Heterophilic interaction with CD177 plays a role in transendothelialmigration of neutrophils. Homophilic ligation ofPECAM1 prevents macrophage-mediated phagocytosis of neighboring viableleukocytes by transmitting a detachment signal. Promotes macrophage-mediated phagocytosis of apoptotic leukocytes bytethering them to the phagocytic cells; PECAM1-mediated detachmentsignal appears to be disabled in apoptotic leukocytes. Modulates bradykinin receptor BDKRB2 activation. Regulates bradykinin- and hyperosmotic shock-inducedERK1/2 activation in endothelial cells. Inducessusceptibility to atherosclerosis. [1-3]

Function of This Protein During Virus Infection
Virus NameSARS-COV-2 Protein Function Anti-viral [4]
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 PECAM1 in viral infection, PECAM1 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 PECAM1 increases SARS-CoV-2 RNA levels compared with control group.
