Rabbit polyclonal to EGFR ( phospho Y1016 )The EGFR, epidermal growth factor receptor, belongs to a family of receptor tyrosine kinases in mammals which is composed of four members: EGFR (ErB1), ErB2, ErB3, and ErB4. EGFR is an 1210 amino acid residue trans-membrane glycoprotein. It consists of an extracellular ligand binding domain, a single alpha helical transmembrane pass, an intracellular tyrosine kinase domain, and a COOH-terminal region that contains autophosphorylation sites. The binding of specific polypeptide ligands, including EGF, transforming growth factor alpha, betacellulin, heparin-binding EGF, epiregulin, or amphiregulin, results in phosphorylation of multiple tyrosine residues in the COOH-terminal tail, such as tyrosine 869Y, 1016Y, 1092Y, 1110Y, 1125Y, 1172Y, 1197Y, etc. The binding of phosphorylated EGFR tyrosines with downstream signaling proteins initiates multiple signaling cascades that culminate in cell proliferation, migration, protein secretion, differentiation and/or oncogenesis. |
