Identification of human cadherin-14, a novel neurally specific type II cadherin, by protein interaction cloning.

Cadherins, a family of Ca2+-dependent cell-cell adhesion molecules, mediate neural cell-cell interactions and may play important roles in neural development. By searching for molecules that interact with beta-catenin, a cytoplasmic regulator of cadherins, we have identified a new member of the cadherin family, which we named human cadherin-14. Cadherin-14 had high amino acid sequence homology with the type II subgroup of cadherins and was broadly expressed in the central nervous system. Cadherin-14 is a novel neurally specific cell-cell adhesion molecule and may regulate neural morphogenesis.
