Description
Purified anti-EGF. Epidermal growth factor (EGF) is a small 6 kD polypeptide and has six conserved cysteine residues that form three intramolecular disulfide bonds. Human EGF is synthesized as transmembrane precursor proteins (1207 amino acids), which are proteolytically cleaved to generate the 54 amino acid mature EGF. EGF/EGF receptor signaling pathway plays an important role in proliferation, differentiation, and migration of a variety of cell types, especially in epithelial cells. The binding of EGF to EGFR induces receptor dimerization, which is required for activating the tyrosine kinase dimerization in the receptor cytoplasmic domain. In addition, the binding of EGF to its receptor triggers several signal transduction pathways including JAK/STAT, Ras/ERK/, and PI3K/AKT pathways. The blocking of the EGF/EGFR pathway can suppress some tumor cell proliferation.
