Previously, we have demonstrated that the tyrosine phosphorylated hepatocyte growth factor receptor (Met) binds to the c-Cbl phosphotyrosine-recognition, tyrosine kinase binding (TKB) domain in a reverse orientation compared to other c-Cbl binding partners. A Met peptide with the DpYR motif changed to RpYD (MetRD) retains a similar TKB binding affinity as the native Met peptide. However, the TKB: MetRD complex crystal structure reveals a complete reversal of the binding orientation. Collated data indicates that both binding and orientation is dictated by the phosphorylated tyrosine and an adjacent arginine forming intra-peptide hydrogen bonds and aligning unidirectionally with complementary charges in the phosphotyrosine binding pocket of c-Cbl.
