epidermal growth factor receptor

epidermal growth factor receptor (EGFR),

receptor often upregulated in epithelial tumors.
Farlex Partner Medical Dictionary © Farlex 2012


A gene on chromosome 7p12 that encodes epidermal growth factor, a transmembrane glycoprotein of the protein kinase superfamily, which is a receptor for members of the epidermal growth factor family. Binding of the protein to a ligand induces receptor dimerisation and tyrosine autophosphorylation and leads to cell proliferation.

EGFR mutations are associated with lung cancer.
