Abstract

The way to a 14-3-3 binder: A fragment-based combinatorial small-molecule microarray generates affinity-based fingerprints of the 14-3-3σ protein. One small molecule (see picture; in red box) that disrupts the 14-3-3/protein interaction (green/blue) has been identified. The compound is cell-permeable and possesses both in vitro and in-cell activities.
