Figure 6. Correlation of the autoinhibited conformation of X11 with the target-binding property of the protein. The C termini of presenilin (DQLAFHQFYI) and calcium channel (HHPDQDHWC) were fused to glutathione S-transferase, respectively. Purified recombinant GST fusion proteins were used for binding assays with wild-type (WT) X11 and its various mutants, including Y836E, Y836F, PDZ1^* (PDZ1 deficient in ligand binding), PDZ2^* (PDZ2 deficient in ligand binding) and PDZ12^* (PDZ2 with both its ligand binding sites disrupted). The amount of X11 protein was detected by immunoblotting with antibody to c-Myc (9E10).
