NCIt definition : Platelet endothelial cell adhesion molecule (738 aa, 83 kDa) is encoded by the human
PECAM1 gene. This protein is involved in leukocyte transendothelial migration and
angiogenesis.;
NCIt note : Cell adhesion molecules present on virtually all monocytes, platelets, and granulocytes.
CD31 is highly expressed on endothelial cells and concentrated at the junctions between
them.;
