Determination of C-Terminal δ-Catenin Responsible for Inducing Dendritic Morphogenesis.

δ-Catenin induces dendritic morphogenesis in several cells and it was reported that deletion of C-terminal 207 amino acid of δ-catenin completely abolished the dendritic morphogenesis. However, exact domain responsible for inducing dendritic morphogenesis in C-terminus of δ-catenin was not mapped. Here, we report that expression of ΔC47 (lacking 47 amino acid of C-terminus: 1-1200), ΔC77 (lacking 77 amino acid of C-terminus: 1-1170) deletion mutants of δ-catenin induced the dendritic morphogenesis of HEK293T and NIH3T3 cells as full-length δ-catenin did.
