Anti-Epidermal Growth Factor Receptor, phosphorylated (Tyr1068) (erbB, EGFR)

Epidermal Growth Factor Receptor, also known as ErbB-1 (EGFR, a 185kD glycoprotein) is a transmembrane tyrosine kinase that regulates a variety of biological responses ranging from mitogenesis to stress signaling. The EGFR consists of a large extracellular domain, a single transmembrane domain and a cytoplasmic domain that exhibits kinase activity. Upon binding of EGF to the extracellular domain, the receptor undergoes dimerization and becomes phosphorylated on several tyrosine residues within the cytoplasmic domain. These events result in EGFR activation and increased tyrosine kinase activity toward a variety of intracellular substrates. Tyrosine 1068 within the cytoplasmic domain of the receptor is a major autophosphorylation site that allows binding of Grb2 and activation of the Ras Raf ERK1&2 signaling pathway.
