The crystal structure of the kinase domain from the epidermal growth, factor receptor (EGFRK) including forty amino acids from the, carboxyl-terminal tail has been determined to 2.6-A resolution, both with, and without an EGFRK-specific inhibitor currently in Phase III clinical, trials as an anti-cancer agent, erlotinib (OSI-774, CP-358,774, Tarceva(TM)). The EGFR family members are distinguished from all other, known receptor tyrosine kinases in possessing constitutive kinase activity, without a phosphorylation event within their kinase domains. Despite its, lack of phosphorylation, we find that the EGFRK activation loop adopts a, conformation similar to that of the phosphorylated active form of the, kinase domain from the insulin receptor. Surprisingly, key residues of a, putative dimerization motif lying between the EGFRK domain and, carboxyl-terminal substrate docking sites are found in close contact with, the kinase domain. Significant intermolecular contacts involving the, carboxyl-terminal tail are discussed with respect to receptor, oligomerization.

Epidermal Growth Factor Receptor tyrosine kinase domain with 4-anilinoquinazoline inhibitor erlotinib

Contents

Overview

The crystal structure of the kinase domain from the epidermal growth factor receptor (EGFRK) including forty amino acids from the carboxyl-terminal tail has been determined to 2.6-A resolution, both with and without an EGFRK-specific inhibitor currently in Phase III clinical trials as an anti-cancer agent, erlotinib (OSI-774, CP-358,774, Tarceva(TM)). The EGFR family members are distinguished from all other known receptor tyrosine kinases in possessing constitutive kinase activity without a phosphorylation event within their kinase domains. Despite its lack of phosphorylation, we find that the EGFRK activation loop adopts a conformation similar to that of the phosphorylated active form of the kinase domain from the insulin receptor. Surprisingly, key residues of a putative dimerization motif lying between the EGFRK domain and carboxyl-terminal substrate docking sites are found in close contact with the kinase domain. Significant intermolecular contacts involving the carboxyl-terminal tail are discussed with respect to receptor oligomerization.
