Identification of a novel HER3 activating mutation homologous to EGFR-L858R in lung cancer
[Paper-level Aggregated] PMCID: PMC4823091
Evidence Type(s): Functional
Summary: Mutation: V855A | Summary: The V855A mutation alters the molecular function of the HER3 protein, affecting its phosphorylation levels, growth response, and colony formation ability in various cellular contexts. It enhances the interaction with HER2 and trans-phosphorylation, indicating significant changes in molecular or biochemical function. Additionally, in silico modeling suggests alterations in the kinase domain and carboxyl-terminal end of the HER3 protein.
Evidence Type: Functional Mutation: L858 | Summary: The L858 mutation is part of a conserved sequence motif that stabilizes the inactive position of the alphaC helix, indicating potential functional relevance.
Evidence Type: Functional Mutation: L597V | Summary: The L597V mutation is associated with increased ERK activation, indicating a functional alteration in molecular activity.
