E-Cadherin activation
Structural highlights
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 Check, as determined by ConSurfDB.

Publication Abstract from PubMedCellular adhesion by classical cadherins depends critically on the exact proteolytic removal of their N-terminal prosequences. In this combined solution NMR and X-ray crystallographic study, the consequences of propeptide cleavage of an epithelial cadherin construct (domains 1 and 2) were followed at atomic level. At low protein concentration, the N-terminal processing induces docking of the tryptophan-2 side-chain into a binding pocket on the same molecule. At high concentration, cleavage induces dimerization (KD=0.72 mM, k(off)=0.7 s(-1)) and concomitant intermolecular exchange of the betaA-strands and the tryptophan-2 side-chains. Thus, the cleavage represents the switch from a nonadhesive to the functional form of cadherin.
