• Post Translation Modifications
• Phosphorylated on Ser and Tyr residues after cellular activation by src kinases (PubMed:21464369, PubMed:9298995, PubMed:19342684, PubMed:18710921).
  Upon activation, phosphorylated on Ser-729 which probably initiates the dissociation of the membrane-interaction segment (residues 709-729) from the cell membrane allowing the sequential phosphorylation of Tyr-713 and Tyr-690 (PubMed:21464369).
  Constitutively phosphorylated on Ser-734 in resting platelets (PubMed:21464369).
  Phosphorylated on tyrosine residues by FER and FES in response to FCER1 activation (By similarity).
  In endothelial cells Fyn mediates mechanical-force (stretch or pull) induced tyrosine phosphorylation (PubMed:18710921).
  Palmitoylation by ZDHHC21 is necessary for cell surface expression in endothelial cells and enrichment in membrane rafts.

• NP_000433.4

• Function
• Cell adhesion molecule which is required for leukocyte transendothelial migration (TEM) under most inflammatory conditions (PubMed:19342684, PubMed:17580308).
  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 (PubMed:19342684).
  Trans-homophilic interaction may play a role in endothelial cell-cell adhesion via cell junctions (PubMed:27958302).
  Heterophilic interaction with CD177 plays a role in transendothelial migration of neutrophils (PubMed:17580308).
  Homophilic ligation of PECAM1 prevents macrophage-mediated phagocytosis of neighboring viable leukocytes by transmitting a detachment signal (PubMed:12110892).
  Promotes macrophage-mediated phagocytosis of apoptotic leukocytes by tethering them to the phagocytic cells; PECAM1-mediated detachment signal appears to be disabled in apoptotic leukocytes (PubMed:12110892).
  Modulates bradykinin receptor BDKRB2 activation (PubMed:18672896).
  Regulates bradykinin- and hyperosmotic shock-induced ERK1/2 activation in endothelial cells (PubMed:18672896).
  Induces susceptibility to atherosclerosis (By similarity).
  Isoform Delta15: Does not protect against apoptosis.
