Binds to a large number of partners, usually by recognition of a phosphoserine or phosphothreonine motif. Binding generally results in the modulation of the activity of the binding partner. When bound to KRT17, regulates protein synthesis and epithelial cell growth by stimulating Akt/mTOR pathway (By similarity). p53-regulated inhibitor of G2/M progression. Publication Abstract from PubMed Targeting protein-protein interactions (PPIs) is a promising approach in the development of drugs for many indications. 14-3-3 proteins are a family of phosphoprotein-binding molecules with critical functions in dozens of cell signaling networks. 14-3-3s are abundant in the central nervous system, and the small molecule fusicoccin-A (FC-A), a tool compound that can be used to manipulate 14-3-3 PPIs, enhances neurite outgrowth in cultured neurons. New semisynthetic FC-A derivatives with improved binding affinity for 14-3-3 complexes have recently been developed. Here, we use a series of screens that identify these compounds as potent inducers of neurite outgrowth through a polypharmacological mechanism. Using proteomics and X-ray crystallography, we discover that these compounds extensively regulate the 14-3-3 interactome by stabilizing specific PPIs, while disrupting others. These results provide new insights into the development of drugs to target 14-3-3 PPIs, a potential therapeutic strategy for CNS diseases.
