Cadherins are transmembrane glycoproteins vital in calcium-dependent cell-cell adhesion during tissue differentiation. Cadherins cluster to form foci of homophilic binding units. A key determinant to the strength of the cadherin-mediated adhesion may be by the juxtamembrane region in cadherins. VE-cadherin (Cadherin 5) is the major cadherin found in endothelial cells and has important roles during angiogenesis and maintenance of barrier permeability. The cytoplasmic domain of VE-cadherin comprises the juxtamembrane domain that binds to the p120 catenin, and the carboxylterminal domain that interacts with β- or γ-catenins. Modulation of tyrosine phosphorylation on one or more of the nine tyrosine sites in the cytoplasmic domain may be important for regulating both angiogenesis and permeability. Phosphorylation of Tyr-658 and Tyr-731 alters catenin binding, restores cell migration, and decreases barrier permeability. While VEGF-induced phosphorylation of Tyr-685 occurs through c-Src, and regulates endothelial cell migration, but not permeability.

Western blot image of human umbilical vein endothelial cells. The blots were probed with rabbit polyclonal anti-VE-cadherin (a.a. 770-781) at 1:1000 (lane 1) and 1:4000 (lane 2). In addition, the antibody was used in the presence (lane 4) or absence (lane 3) of blocking peptide.

VE-Cadherin synthetic peptide corresponds to amino acids 770 to 781 in human VE-cadherin. This sequence has significant homology to the conserved site in rat and mouse, and has less than 50% homology with other cadherins.
