EGFR (T790M C797S L858R), Active

产品说明

应用

Useful for kinase assay.

生化/生理作用

Recombinant human EGFR (T790M C797S L858R) (668-end) was expressed by Baculovirus in Sf9 insect cells using an N-terminal GST tag. EGFR is the receptor for members of the EGF family and is a transmembrane glycoprotein that has tyrosine kinase activity. Binding of epidermal growth factor to EGFR induces receptor dimerization and tyrosine autophosphorylation and leads to cell proliferation, differentiation, motility, and cell survival ⁽¹⁾. Activation of EGFR triggers mitogenic signaling in gastrointestinal mucosa, and its expression is upregulated in colon cancers and most neoplasms ⁽²⁾. Activation of EGFR triggers activation of the ERK-signaling pathway in normal gastric epithelial and colon cancer cell lines. Inactivation of EGFR with selective inhibitors significantly reduces ERK2 activation, c-fos mRNA expression and cell proliferation.
