Targeted Protein Localization by Covalent 14-3-3 Recruitment.

ABSTRACT: 14-3-3 proteins have a unique ability to bind and sequester a multitude of diverse phosphorylated signaling proteins and transcription factors. Many previous studies have shown that interactions of 14-3-3 with specific phosphorylated substrate proteins can be enhanced through small-molecule natural products or fully synthetic molecular glue interactions. However, enhancing 14-3-3 interactions with both therapeutically intractable transcription factor substrates and potential neo-substrates to sequester and inhibit their function remains elusive. One of the 14-3-3 proteins, 14-3-3σ or SFN, has cysteine C38 at the substrate-binding interface, near the sites where previous 14-3-3 molecular glues have been found to bind. In this study, we screen a fully synthetic cysteine-reactive covalent lig
