EGFR is a driver of tumorigenesis. EGFR is mainly found in an auto-inhibited, dimerization-incompetent, state at the plasma membrane (PM).

EGFR has multiple mutants. EGFR C797S/L858R Recombinant Human Active Protein Kinase is a recombinant EGFR C797S/L858R protein that can be used to study EGFR C797S/L858R-related functions.
