14-3-3 protein C-terminal stretch occupies ligand binding groove and is displaced by phosphopeptide binding.

Abstract excerpt

14-3-3 proteins are important regulators of numerous cellular signaling circuits. They bind to phosphorylated protein ligands and regulate their functions by a number of different mechanisms. The C-terminal part of the 14-3-3 protein is known to be involved in the regulation of 14-3-3 binding properties. The structure of this region is unknown; however, a possible location of the C-terminal stretch within the...
