背景

The epidermal growth factor (EGF) receptor is a transmembrane tyrosine kinase that belongs to the HER/ErbB protein family. Ligand binding results in receptor dimerization, autophosphorylation, activation of downstream signaling, internalization, and lysosomal degradation (1,2). Phosphorylation of EGF receptor (EGFR) at Tyr845 in the kinase domain is implicated in stabilizing the activation loop, maintaining the active state enzyme, and providing a binding surface for substrate proteins (3,4). c-Src is involved in phosphorylation of EGFR at Tyr845 (5). The SH2 domain of PLCγ binds at phospho-Tyr992, resulting in activation of PLCγ-mediated downstream signaling (6). Phosphorylation of EGFR at Tyr1045 creates a major docking site for the adaptor protein c-Cbl, leading to receptor ubiquitination and degradation following EGFR activation (7,8). The GRB2 adaptor protein binds activated EGFR at phospho-Tyr1068 (9). A pair of phosphorylated EGFR residues (Tyr1148 and Tyr1173) provide a docking site for the Shc scaffold protein, with both sites involved in MAP kinase signaling activation (2). Phosphorylation of EGFR at specific serine and threonine residues attenuates EGFR kinase activity. EGFR carboxy-terminal residues Ser1046 and Ser1047 are phosphorylated by CaM kinase II; mutation of either of these serines results in upregulated EGFR tyrosine autophosphorylation (10). 1.Hackel, P.O. et al.

Immunoprecipitation of EGFR protein from HeLa cell extracts. Lane 1 is 10% input, lane 2 is Rabbit (DA1E) mAb IgG XP® Isotype Control #3900, and lane 3 is EGF Receptor (D38B1) XP® Rabbit mAb. Western blot analysis was performed using EGF Receptor (D38B1) XP® Rabbit mAb. Anti-rabbit IgG, HRP-linked Antibody #7074 was used as a secondary antibody.

Western blot analysis of extracts from serum-starved A431 cells, untreated (-) or treated with hEGF (100 ng/ml, 5 min; +), using EGF Receptor (1F4) Mouse mAb #2239 (Panel A) and Phospho-EGF Receptor (Tyr1068) (D7A5) XP® Rabbit mAb #3777 (Panel B). Anti-rabbit IgG (H+L) (DyLight 800 4X PEG Conjugate) #5151 (green) and Anti-mouse IgG (H+L) (DyLight 680 Conjugate) #5470 (red) were used as secondary antibodies.

Western blot analysis of extracts from control Hela cells (lane 1), or EGFR knockout Hela cells (lane 2) using EGF Receptor (D38B1) XP® Rabbit mAb #4267, (upper) or #8457 β-Actin (D6A8) Rabbit mAb (lower). The absence of signal in EGFR-knockout Hela cells confirms specificity of the antibody for EGFR.
