Target description

Cadherin-1 (UniProt: P12830; also known as CAM 120/80, Epithelial cadherin, E-cadherin, Uvomorulin, CD324) is encoded by the CDH1 (also known as CDHE, UVO) gene (Gene ID: 999) in human. Cadherins are calcium-dependent cell adhesion molecules that participate in cell-cell adhesion during embryogenesis, development, organogenesis, and differentiation. E-cadherin is a single-pass type I membrane glycoprotein with tumor suppressive properties. It is synthesized with a signal peptide (aa 1-22) and a propeptide (aa 23-154) that are subsequently cleaved off to produce the mature form that contains an extracellular domain (aa 155-709), a transmembrane domain (aa 710-730), and a cytoplasmic domain (aa 731-882). N-glycosylation at Asn-637 is shown to be essential for its expression, folding, and trafficking. E-cadherin is known to contain five cadherin domains. Three calcium ions are usually bound at the interface of each cadherin domain and rigidify the connections, imparting a strong curvature to the full-length ectodomain. Post-translationally it can be cleaved into three chains: E-Cad/CTF1 (aa 701-882); E-Cad/CTF2 (aa 732-882); and E-Cad/CTF3 (aa 751-882). During apoptosis or with calcium influx, it is cleaved by a membrane-bound metalloproteinase (ADAM10; at residues 700-701), which causes disruption of cell-cell adhesion and the subsequent release of β-catenin into the cytoplasm. The residual membrane-tethered cleavage product is then rapidly degraded via an intracellular proteolytic pathway. It can also be cleaved by PS1/ -secretase (at residues 731-732) and this cleavage promotes disassembly of adherens junctions. Clone 19A11 is an activating monoclonal antibody that stimulates adhesion of cells to E-cadherin substrate. It modifies the adhesive properties of E-cadherin and prevent the metastatic invasion of mouse lung cancer cells expressing human E-cadherin. This clone is shown to bind to the extracellular domain of E-cadherin near its primary adhesive motif: the strand swap dimer interface, which strengthens adhesion by stabilizing strand-swap dimers.
