The kinase activity is induced by various effectors including AR or MAP2K6/MAPKK6. Phosphorylates the DNA-binding domain of androgen receptor/AR and thereby inhibits AR-mediated transcription. Inhibits also ESR1-mediated transcription. May play a role in cytoskeleton regulation by interacting with IQGAP1. May protect cells from apoptosis through phosphorylation of BAD.<ref>PMID:14573606</ref> <ref>PMID:20054820</ref>

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.
