Background: CD31/PECAM-1

Cluster of differentiation (CD31), Platelet Endothelial Cell Adhesion Molecule 1 (PECAM-1), is a 30kDa type I transmembrane glycoprotein expressed by endothelial cells, platelets, leukocytes and some lymphocytes (e.g., B and T-cell subsets). Structurally, PECAM-1 consists of six extracellular immunoglobulin-like domains which serve to support various functions including homophilic binding, maintaining high expression of PECAM-1 within endothelial intercellular junctions, and supporting endothelial cell migration (1,2). PECAM's homophilic binding underscores its role in vascular barrier integrity and leukocyte trans-endothelial movement. However, PECAM may also engage in heterophilic interactions with molecules such as glycosaminoglycans (GAG), integrin alpha 5 beta 3, CD38 in lymphocytes and CD177/PR3 in neutrophils (2).

PECAM's intracellular cytoplasmic domain consists of a sequence of 118 amino acids and contains serine and tyrosine (also referred to as immunoreceptor tyrosine-based inhibitory motifs-ITIMs) residues, which may be phosphorylated upon cellular stimulation (3). ITIMs are phosphorylated by Src-family kinases and non-Src family kinases (e.g., Csk), leading to a conformational change which supports interactions with Src homology 2 (SH2) domain containing proteins such as protein-tyrosine phosphatase, SHP-2 (1,2). Formation of SHP-2/PECAM-1 complexes induces endothelial cell migration through the dephosphorylation of focal adhesion kinase and regulation of RhoA activity (1). Signaling downstream of ITIM tyrosine phosphorylations also plays a role in PECAM's anti-apoptotic activity, a function which is independent of its interaction with SHP-2. In platelets and leukocytes, phosphorylation of PECAM's cytosolic domain is inhibitory, preventing their activation.
