14-3-3 proteins bind phosphorylated binding partners to regulate several of their properties, including enzymatic activity, stability and subcellular localization. Here, two crystal structures are presented: the crystal structures of the 14-3-3 protein (also known as Bmh1) from the yeast Lachancea thermotolerans in the unliganded form and bound to a phosphopeptide derived from human PI4KB (phosphatidylinositol 4-kinase B). The structures demonstrate the high evolutionary conservation of ligand recognition by 14-3-3 proteins. The structural analysis suggests that ligand recognition by 14-3-3 proteins evolved very early in the evolution of eukaryotes and remained conserved, underlying the importance of 14-3-3 proteins in physiology.
