Chemical genetics strategy to profile kinase target engagement reveals role of FES in neutrophil phagocytosis

Abstract

Chemical tools to monitor drug-target engagement of endogenous enzymes are essential for preclinical target validation. Here, the authors present a chemical genetics strategy to study target engagement of endogenous kinases, achieving specific labeling and inactivation of FES kinase to provide insights into FES’ role in neutrophil phagocytosis.
