Cadherin-2 (CDH2), also known as neural cadherin (NCAD) is a protein that in humans is encoded by the CDH2 gene.[1][2] CDH2 has also been designated as CD325 (cluster of differentiation 325).


Cadherin 2 a classical cadherin from the cadherin superfamily. Cadherin 2 is a calcium dependent cell-cell adhesion glycoprotein comprising five extracellular cadherin repeats, a transmembrane region and a highly conserved cytoplasmic tail. The protein functions during gastrulation and is required for establishment of left-right asymmetry. At certain central nervous system synapses, presynaptic to postsynaptic adhesion is mediated at least in part by this gene product.[3]

N-cadherins interact with catenins to play an important role in learning and memory (For full article see Cadherin-catenin complex in learning and memory).

Role in cancer metastasis[edit]

N-Cadherin is commonly found in cancer cells and provides a mechanism for transendothelial migration. When a cancer cell adheres to the endothelial cells of a blood vessel it up-regulates the src kinase pathway, which phosphorylates beta-catenins attached to both N-cadherin (this protein) and E-cadherins. This causes the intercellular connection between two adjacent endothelial cells to fail and allows the cancer cell to slip through.[4]
