Recombinant Human EGFR Isoform vIII Protein (Leu25-Ser378), C-Fc and Avi-tagged, Biotinylated conjugated
Product Description
Cat
IMP-10042
Official Symbol
EGFR
Product Overview
Biotinylated recombinant human EGFR Isoform vIII protein (Leu25-Ser378) with a human IgG1 (Pro100-Lys330) Fc tag and Avi tag at C-terminus was expressed in Chinese Hamster Ovary cell line.
Description
The protein encoded by this gene is a transmembrane glycoprotein that is a member of the protein kinase superfamily. This protein is a receptor for members of the epidermal growth factor family. EGFR is a cell surface protein that binds to epidermal growth factor, thus inducing receptor dimerization and tyrosine autophosphorylation leading to cell proliferation. Mutations in this gene are associated with lung cancer. EGFR is a component of the cytokine storm which contributes to a severe form of Coronavirus Disease 2019 (COVID-19) resulting from infection with severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2).
