epidermal growth factor receptor

epidermal growth factor receptor (EGFR),

[MIM*131550]
receptor often upregulated in epithelial tumors.

EGFR

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.

Molecular pathology
EGFR mutations are associated with lung cancer.

The highly expressed growth factor receptor genes, meanwhile, were platelet-derived growth factor receptor-like protein, platelet-derived growth factor receptor (beta polypeptide), autocrine motility factor receptor, transforming growth factor beta type 2 receptor, epidermal growth factor receptor, and insulin-like growth factor 2 receptor (IGF2R).
In the case of epidermal growth factor receptor, epidermal growth factor stimulates its receptor to autophosphorylate tyrosine sites in the cytoplasmic portion of the receptor.[16] This in turn stimulates activation of guanine nucleotide exchange factors, which promote the formation of the active guanosine triphosphate (GTP)-bound form of Ras.
JuneBiedler of Memorial Sloan-Kettering Cancer Center in New York studied 12 cell lines from mouse, human and hamster cancers and found that not only p-glycoprotein but also another protein, sorcin, and a cell membrane receptor, epidermal growth factor, were present in high concentrations.
