Structural Basis for Human PECAM-1-Mediated Trans-homophilic Cell Adhesion
Cell adhesion involved in signal transduction, tissue integrity and pathogen infection is mainly mediated by cell adhesion molecules (CAM). One CAM member, platelet-endothelial-cell adhesion molecule-1 (PECAM-1), plays an important role in tight junction among endothelia cells, leukocyte trafficking, and immune response through its homophilic and heterophilic binding patterns. Both kinds of int...
متن کاملFunctional analysis of the structural basis of homophilic cadherin adhesion.
The structures of many cell surface adhesion proteins comprise multiple tandem repeats of structurally similar domains. In many cases, the functional significance of this architecture is unknown, and there are several cases in which evidence for individual domain involvement in adhesion has been contradictory. In particular, the extracellular region of the adhesion glycoprotein cadherin consist...
متن کاملPlatelet Endothelial Cell Adhesion Molecule-1 (PECAM-1) Homophilic Adhesion Is Mediated by Immunoglobulin-like Domains
PECAM-1/CD31 is vascular cell adhesion and signaling molecule of the Ig superfamily that plays a role in neutrophil recruitment at inflammatory sites and may be involved the release of leukocytes from the bone marrow and in cardiovascular development. The interactions of PECAM-1 with its ligands are complex in that it is able to bind both with itself (homophilic adhesion) or with non-PECAM-1 li...
متن کاملResidues on both faces of the first immunoglobulin fold contribute to homophilic binding sites of PECAM-1/CD31.
CD31 (PECAM-1) is a member of the immunoglobulin superfamily whose extracellular domain is comprised of six immunoglobulin-like domains. It is widely expressed on endothelium, platelets, around 50% of lymphocytes, and cells of myeloid lineage. CD31 has been shown to be involved in interendothelial adhesion and leukocyte-endothelial interactions, particularly during transmigration. CD31-mediated...
متن کاملPECAM-1/CD31 trans-homophilic binding at the intercellular junctions is independent of its cytoplasmic domain; evidence for heterophilic interaction with integrin alphavbeta3 in Cis.
PECAM-1/CD31 is a cell adhesion and signaling molecule that is enriched at the endothelial cell junctions. Alternative splicing generates multiple PECAM-1 splice variants, which differ in their cytoplasmic domains. It has been suggested that the extracellular ligand-binding property, homophilic versus heterophilic, of these isoforms is controlled by their cytoplasmic tails. To determine whether...
