Description
As a member of the epidermal growth factor receptor (EGFR) family, EGFR protein is type I transmembrane glycoprotein that binds a subset of EGF family ligands including EGF, amphiregulin, TGF-α, betacellulin, etc. EGFR protein plays a crucial role in signaling pathway in the regulation of cell proliferation, survival and differentiation. Binding of a ligand induces EGFR protein homo-or heterodimerization, the subsequent tyrosine autophosphorylation and initiates various down stream pathways (MAPK, PI3K/PKB and STAT). In addition, EGFR signaling also has been shown to exert action on carcinogenesis and disease progression, and thus EGFR protein is proposed as a target for cancer therapy currently.
Form
Lyophilized from sterile PBS, pH7.4, 5 % trehalose, 5% mannitol and 0.01% Tween80.
Molecular Mass
The recombinant human EGFR consists of 630 amino acids and has a calculated molecular mass of 69.8 kDa. As a result of glycosylation, it migrates as an approximately 99.5 kDa protein in SDS-PAGE under reducing conditions.
