Schematic representation of cadherin constructs used in this study. Full length N-cadherin and a chimera consisting of the extracellular and transmembrane domains of IL-2Rα and the intracellular domain of N-cadherin (amino acids 752–912) (ILR/N-cad) are shown. The cytoplasmic domain of N-cadherin was tagged with flag [N-cad (tail)] or was fused to the C terminus of GFP (NT). Fragments of the cytoplasmic N-cadherin tail (N71, amino acids 842–912; N30, amino acids 862–891), the E-cadherin tail (ET, amino acids 735–844), and two fragments from this domain (E72, amino acids 813–844; E30, amino acids 833–862) were fused to the C terminus of GFP.
