Cadherin-5 (CDH5)

They preferentially interact with themselves in a homophilic manner in connecting cells; cadherins may thus contribute to the sorting of heterogeneous cell types. This cadherin may play a essential role in endothelial cell biology through control of the cohesion and organization of the intercellular junctions.

It partners with alpha-catenin forming a link to the cytoskeleton. Acts in concert with KRIT1 to establish and maintain correct endothelial cell polarity and vascular lumen.
