Both of the 14-3-3 binding motifs in Snail are required for optimal interaction with 14-3-3 proteins. (A) The truncated forms of Snail used. (B) Interaction of 14-3-3 proteins with truncated Snail variants. The “*” indicates a non-specific band. (C) Single amino acid substitutions in the 14-3-3 binding motifs of Snail. The core serine in the NH2-terminal motif and the threonine in the COOH-terminal motif were replaced with alanines, respectively. (D) The SNA-A and SNA-B sites are required for optimal 14-3-3 protein binding.
