FunctionInduces susceptibility to atherosclerosis (By similarity). Cell adhesion molecule which is required for leukocyte transendothelial migration (TEM) under most inflammatory conditions. Tyr-690 plays a critical role in TEM and is required for efficient trafficking of PECAM1 to and from the lateral border recycling compartment (LBRC) and is also essential for the LBRC membrane to be targeted around migrating leukocytes. Prevents phagocyte ingestion of closely apposed viable cells by transmitting 'detachment' signals, and changes function on apoptosis, promoting tethering of dying cells to phagocytes (the encounter of a viable cell with a phagocyte via the homophilic interaction of PECAM1 on both cell surfaces leads to the viable cell's active repulsion from the phagocyte. During apoptosis, the inside-out signaling of PECAM1 is somehow disabled so that the apoptotic cell does not actively reject the phagocyte anymore. The lack of this repulsion signal together with the interaction of the eat-me signals and their respective receptors causes the attachment of the apoptotic cell to the phagocyte, thus triggering the process of engulfment). Isoform Delta15 is unable to protect against apoptosis. Modulates BDKRB2 activation. Regulates bradykinin- and hyperosmotic shock-induced ERK1/2 activation in human umbilical cord vein cells (HUVEC).
-
Tissue specificityExpressed on platelets and leukocytes and is primarily concentrated at the borders between endothelial cells. Isoform Long predominates in all tissues examined. Isoform Delta12 is detected only in trachea. Isoform Delta14-15 is only detected in lung. Isoform Delta14 is detected in all tissues examined with the strongest expression in heart. Isoform Delta15 is expressed in brain, testis, ovary, cell surface of platelets, human umbilical vein endothelial cells (HUVECs), Jurkat T-cell leukemia, human erythroleukemia (HEL) and U937 histiocytic lymphoma cell lines (at protein level).

Sequence similaritiesContains 6 Ig-like C2-type (immunoglobulin-like) domains.
-
DomainThe Ig-like C2-type domains 2 and 3 contribute to formation of the complex with BDKRB2 and in regulation of its activity.
-
Post-translational
modificationsPhosphorylated on Ser and Tyr residues after cellular activation. In endothelial cells Fyn mediates mechanical-force (stretch or pull) induced tyrosine phosphorylation. -
Cellular localizationMembrane. Cell junction. Localizes to the lateral border recycling compartment (LBRC) and recycles from the LBRC to the junction in resting endothelial cells and Cell junction.

Following heat mediated antigen retrieval the tissue was formaldehyde fixed and blocked with serum. The tissue was incubated with the primary antibody for 20 minutes. A biotinylated goat anti-rabbit antibody was used as the secondary. The endothelium of vessels of any tissues are positive.

White dotted lines indicate the graft wall. Scale bar = 100 μm.
Explanted grafts from C57/BL6 mice were fixed overnight in paraformaldehyde (2%) at room temperature. Samples were dehydrated through an ethanol gradient and embedded in paraffin and sectioned at 5 μm transversely from proximal anastomosis to distal anastomosis. For immunohistochemistry staining, sections were deparaffinised and stained with antibody against CD31 (Abcam, ab28364, 1:200) for endothelial cells.

Tissue samples were fixed by perfusion with paraformaldehyde, cut into 20 micron slices and blocked with 1% BSA for 60 minutes at 21°C. Antigen retrieval was by heat mediation in a Tris/EDTA pH9 buffer. The sample was incubated with primary antibody (20 ug/mL) at 4°C for 16 hours. A HRP-conjugated goat anti-rabbit polyclonal (2 ug/mL) was used as the secondary antibody.

For immunofluorescence staining, the skin samples were fixed in 4% paraformaldehyde and embedded in paraffin. Skin sections were stained with an anti-GFP antibody. The skin sections were also treated with primary Abs against CD31 (Abcam, ab28364, diluted 1:300). Secondary antibodies conjugated to rhodamine-isothiocyanate were used for fluorescence detection on a confocal laser scanning fluorescence microscope (Zeiss, German).
