== Publication Abstract from PubMed ==
The cadherins mediate cell adhesion and play a fundamental role in normal development. They participate in the maintenance of proper cell-cell contacts: for example, reduced levels of epithelial cadherin (E-cadherin) correlate with increased invasiveness in many human tumour cell types. The cadherins typically consist of five tandemly repeated extracellular domains, a single membrane-spanning segment and a cytoplasmic region. The N-terminal extracellular domains mediate cell-cell contact while the cytoplasmic region interacts with the cytoskeleton through the catenins. Cadherins depend on calcium for their function: removal of calcium abolishes adhesive activity, renders cadherins vulnerable to proteases (reviewed in ref. 4) and, in E-cadherin, induces a dramatic reversible conformational change in the entire extracellular region. We report here the X-ray crystal structure at 2.0 A resolution of the two N-terminal extracellular domains of E-cadherin in the presence of calcium. The structure reveals a two-fold symmetric dimer, each molecule of which binds a contiguous array of three bridged calcium ions. Not only do the bound calcium ions linearize and rigidify the molecule, they promote dimerization. Although the N-terminal domain of each molecule in the dimer is aligned in a parallel orientation, the interactions between them differ significantly from those found in the neural cadherin (N-cadherin) N-terminal domain (NCD1) structure. The E-cadherin dual-domain structure reported here defines the role played by calcium in the cadherin-mediated formation and maintenance of solid tissues.

Function

CADH1_MOUSE Cadherins are calcium-dependent cell adhesion proteins. They preferentially interact with themselves in a homophilic manner in connecting cells; cadherins may thus contribute to the sorting of heterogeneous cell types. CDH1 is involved in mechanisms regulating cell-cell adhesions, mobility and proliferation of epithelial cells. Has a potent invasive suppressor role. It is a ligand for integrin alpha-E/beta-7 (By similarity). E-Cad/CTF2 promotes non-amyloidogenic degradation of Abeta precursors. Has a strong inhibitory effect on APP C99 and C83 production (By similarity).

Evolutionary Conservation
