title: cDNA cloning, chromosomal mapping, and expression analysis of human VE-Cadherin-2.
abstract: Murine vascular endothelial cadherin-2 (VE-cad-2) is a cellular adhesion molecule that is distinct from vascular endothelial cadherin 1 (VE-cad-1) in that it does not interact with catenins and does not appear to affect cell migration or growth. In this study, we have cloned a full-length cDNA of the human homolog of VE-cad-2 and used it to map the chromosomal locus of the VE-cad-2 gene. Human VE-cad-2 maps to Chromosome (Chr) 5q31. The cDNA of human VE-cad-2 is highly homologous to mouse VE-cad-2, except for a C-terminal tail. The genomic structure of VE-cad-2 is strikingly similar to that reported for a large family of neuronal protocadherin genes mapped to Chr 5q, yet the amino acid sequences between VE-cad-2 and the protocadherins are substantially divergent. The promoter of human VE-cad-2 contains two TATA boxes and transcription initiates from a single site 3' to these elements. Similar to mouse VE-cad-2, the human gene is expressed primarily in highly vascularized tissues.
