Recombinant Human Cadherin-6/KCAD Fc Chimera Protein, CF Summary

Details of Functionality
Measured by the ability of the immobilized protein to support the adhesion of Caki‑2 human clear cell carcinoma epithelial cells. When 5 x 104 cells/well are added to Recombinant Human Cadherin-6 Fc Chimera coated plates (5 µg/mL with 100 µL/well), >30% of cells will adhere after 30 minutes at 37° C.
Optimal concentration depends on cell type as well as the application or research objectives.

Cadherin-6, also known as KCAD or K-Cadherin, is a 110-120 kDa type I transmembrane glycoprotein belonging to the classical Cadherin superfamily of calcium-dependent adhesion molecules. Cadherins are involved in multiple processes including embryonic development, cell migration, and maintenance of epithelial integrity (1, 2). Human Cadherin-6 is synthesized with an 18 amino acid (aa) signal peptide and a 35 aa N-terminal propeptide. The mature cell surface-expressed protein consists of a 562 amino acid (aa) extracellular domain (ECD) that contains five tandem Cadherin repeats, a 21 aa transmembrane segment, and a 154 aa cytoplasmic domain (3). Within the ECD, human Cadherin-6 shares 96% and 98% aa sequence identity with mouse and rat Cadherin-10, respectively. Alternate splicing of the human Cadherin-6 mRNA generates additional isoforms with deletions in the extracellular region or a substituted and truncated cytoplasmic domain (4). It interacts homotypically as well as heterotypically with Cadherin-9 and more weakly with Cadherins-7, -10, and -14 (5, 6). Cadherin-6 is expressed primarily in the kidney and brain, both during development and in the adult (3, 7-9). It is enriched in renal proximal tubule epithelial cells and their precursors at sites of cell-cell contact as well as on basolateral membranes (8, 10, 11). In the nervous system, Cadherin-6 is neuronally expressed in discrete regions of the neural plate, neural crest cells that give rise to peripheral nerves, and the brain (7, 12). Cadherin-6 is additionally expressed in the developing retina, osteoclasts and their progenitors, ovarian epithelium, and endometrium during the follicular phase of the menstrual cycle (4, 13-15). It is also expressed in carcinomas of the kidney, ovary, and liver (3, 10, 11, 14).
