CDH1, also known as cadherin-1, is a member of cell surface glycoproteins that meditate cell adhesion. Human CDH1 shares amino acid sequence identity with the rat and mouse proteins. It is a single-pass transmembrane protein that meditates calcium-dependent epithelial cell adhesion. This protein preferentially interacts with themselves in a homophilic manner in connecting cells. It may thus contribute to the sorting of heterogeneous cell types. It is involved in mechanisms regulating cell-cell adhesions, mobility and proliferation of epithelial cells. It is a ligand for integrin alpha-E/beta-7. Recombinanat human CDH1, fused to His-tag at C-terminus, was expressed in insect cell and purified by using conventional chromatography techniques.
