Figure 5. Mutational Analysis of Type II Cadherin Specificity Using SPR.
(A) SPR responses of wild-type or specificity mutants of cadherin-6 and cadherin-11 (columns) passed over wild-type cadherin-6, cadherin-9, cadherin-10, cadherin-8, and cadherin-11 surfaces (rows).
(B) Chimeric proteins cad-6EC111EC2 and cad-11EC16EC2 passed over the same surfaces reproduce the binding characteristics of the wild-type proteins with corresponding EC1 domains.
All mutant and chimeric proteins retained homophilic binding in AUC (Table 1).
