Engineering soluble artificial epidermal growth factor receptor mimics capable of spontaneous in vitro dimerization.

Epidermal growth factor receptor (EGFR) is a clinically validated target for a multitude of human cancers. The receptor is activated upon ligand binding through a critical dimerization step. Dimerization can be replicated in vitro by locally concentrating the receptor kinase domains on the surface of lipid-based vesicles.
