Transmwembrane signaling by the epidermal growth factor receptor (EGFR) involves ligand-induced dimerization and allosteric regulation of the intracellular tyrosine kinase domain. Crystallographic studies have shown how ligand binding induces dimerization of the EGFR extracellular region but cannot explain the "high-affinity" and "low-affinity" classes of cell-surface EGF-binding sites inferred from curved Scatchard plots. From a series of crystal structures of the Drosophila EGFR extracellular region, we show here how Scatchard plot curvature arises from negatively cooperative ligand binding. The first ligand-binding event induces formation of an asymmetric dimer with only one bound ligand. The unoccupied site in this dimer is structurally restrained, leading to reduced affinity for binding of the second ligand, and thus negative cooperativity. Our results explain the cell-surface binding characteristics of EGF receptors and suggest how individual EGFR ligands might stabilize distinct dimeric species with different signaling properties.

A sound rationale exists for antibody targeting of the MET receptor tyrosine kinase, but therapeutic agents that can broadly block HGF ligand binding and exon 14-mutated or amplified MET to induce receptor degradation have yet to be reported. Here we report the identification of several MET monoclonal antibodies (mAb) that block MET dependent signaling and tumor growth. In particular, the MET mAb KTN0073 and KTN0074 bind the Sema/PSI domain, at overlapping but distinct epitopes, preventing HGF interaction with MET and triggering receptor ubiquitination and degradation. Notably, both mAbs also triggered degradation of oncogenic METexon 14 mutants, which propagate more durable MET signals due to a defect in receptor degradation. Mechanistic investigations showed that both mAbs engaged a pathway distinct from HGF induced receptor degradation and protease mediated shedding, independently of signaling driven by the exon 14-encoded sequences in the intracellular juxtamembrane region of the MET receptor. Grafting the mAb variable regions onto the IgG2 constant region dramatically enhanced the tumor inhibitory activities of KTN0073 but not KTN0074, suggesting a specific influence of antibody isotype of the epitopes for these two MET mAbs. Overall, our results highlight KTN0073 as a novel IgG2 based MET mAb that acts through exon 14-independent mechanisms to degrade the MET receptor, potentially offering a therapeutic tool to treat a broader range of human tumors where MET is exon 14 mutated or amplified. © 2016 AACR.
