Human N-Cadherin Propeptide Antibody

N‑Cadherin (Neural Cadherin; also CD325 and Cadherin-2) is a 130‑135 kDa member of the "classical" (or type I) cadherin subfamily, cadherin superfamily of proteins. It is expressed on multiple cell types, including neurons, fibroblasts, Schwann cells, endothelial cells and hepatic stellate cells. N‑Cadherin mediates homotypic binding, either in cis (same cell) or trans (adjacent cell). proN‑Cadherin is expressed as an 881 amino acid (aa) type I transmembrane glycoprotein. It may be initially inserted into the ER, where the 15‑20 kDa prodomain (aa 26‑159) is cleaved by proprotein convertase, and the mature molecule is transported to the surface. Alternatively, on neurons, proN‑Cadherin may first appear on the surface, with cleavage occurring at the time of synaptogenesis. Cleavage appears necessary for homophilic interaction as presence of the prodomain is suggested to negatively regulate oligomer formation. Over the entire prodomain, the human N‑Cadherin proregion shares 87% aa identity with the mouse N‑Cadherin proregion.
