Cadherin Peptide, avian, (C44H75N17O13), a peptide with the sequence Leu-Arg-Ala-His-Ala-Val-Asp-Val-Asn-Gly-NH2, MW= 1050.2. Cadherins (named for "calcium-dependent adhesion") are a class of type-1 transmembrane proteins. They play important roles in cell adhesion, ensuring that cells within tissues are bound together. They are dependent on calcium (Ca2+) ions to function. Cadherins are synthesized as polypeptides and undergo many post-translational modifications to become the proteins which mediate cell-cell adhesion and recognition. Cadherins behave as both receptors and ligands. During development, their behavior assists in properly positioning cells - they are responsible for the separation of the different tissue layers, and for cellular migration. In the very early stages of development, E-cadherin (epithelial cadherin) is most greatly expressed. During the next stage, the development of the neuronal plate, N-cadherin (neural cadherin) is expressed and there is a decrease in E-cadherin. Finally, during the development of the notochord and the condensation of somites, E- P- and N-cadherin expression increases. After development, cadherins play a role in maintaining cell and tissue structure, and in cellular movement.
