Schematic representation of N-cadherin wild-type and mutated constructs and coimmunoprecipitation experiments. A, The constructs of wild-type N-cadherin (NWT), EC1 domain deletion (NΔEC1), Trp-2 mutated to Ala in N-cadherin (NW2A), and a chimeric molecule of E-cadherin whose EC1 domain was replaced by the N-cadherin EC1 domain (ENEC1). B, Western blot analysis of lysates and immunoprecipitates from LR/N, LR/NΔEC1, and LR/NW2A cells. C, Four LR/NW2A clones expressing different levels of R- and N-cadherin (NW2A) were detected, and then immunoprecipitated by GFP antibody and analyzed by immunoblotting.
