EGFR Phospho (Tyr1068) Antibody from BIOLEGEND

Epidermal growth factor receptor (EGFR) is a receptor tyrosine kinase that links extracellular mitogenic ligand binding to complex downstream signaling cascades. Initial ligand binding results in receptor oligomerization and autophosphorylation of multiple tyrosine residues within cytosolic domains of the protein. Phosphorylation at tyrosine 1068 allows for binding directly to the adaptor protein GRB2. EGFR stimulation leads to activation of RAS-RAF-MEK-ERK, PI3 kinase-AKT, PLCγ-PKC and STAT signaling cascades, and constitutive activation of the receptor promotes tumorigenesis in multiple cancers.
