PECAM-mediated adhesion is complex, because it is capable of binding both to itself (homophilic adhesion) and to non-PECAM ligands (heterophilic adhesion). The trans-homophilic interaction between the two PECAM-1 molecules is mediated by their NH2-terminal membrane distal Ig homology domains 1 and 2 plus the proper spacing formed by the six Ig-homology domains.
