Cadherin-2 (UniProt P19022; also known as CD325, CDw325, N-cadherin, Neural cadherin) is encoded by the CDH2 (also known as CDHN, NCAD) gene (Gene ID 1000) in human. N-Cadherin is a single-pass type I membrane protein that plays a role in calcium-dependent cell adhesion. N-cadherins preferentially interacts with themselves in a homophilic manner in connecting cells; may thus contribute to the sorting of heterogeneous cell types. Cadherins are synthesized as precursor proteins that are proteolytically cleaved to generate functional, mature proteins. Newly synthesized proN-cadherin (a.a. 1-906) is phosphorylated and proteolytically processed prior to transport to the plasma membrane. Cadherins are composed of an extracellular domain (a.a. 160-724 of human N-cadherin) with five homologous repeats that mediates adhesion, a single pass transmembrane domain (a.a. 725-745 of human N-cadherin), and a conserved cytoplasmic domain (a.a. 746-906 of human N-cadherin) that interacts with catenins to link cadherins to the actin cytoskeleton. N-cadherin is well expressed in endothelial cells and plays an essential role in the maturation and stabilization of normal vessels. However, it also promotes tumor cell survival, migration and invasion, and a high level of its expression is often associated with poor prognosis.
