PubMed Abstract:
Extracellular signal-regulated kinase 2 (ERK2) controls vital physiological processes involving proliferation and differentiation and is a drug target molecule for many diseases such as cancers. In silico screening focusing on an allosteric site that plays a crucial role in substrate anchoring conferred an ERK2 inhibitor (compound 1). However, a competitive binding assay indicated that compound 1 did not bind to the allosteric site. Here, the crystal structure of ERK2 in complex with compound 1 revealed a novel binding site. This finding demonstrates the feasibility of developing new types of ERK2 inhibitors.
