Testing Data

(Phospho-HER4-Y1162 Antibodywas used to detect Phospho-HER4-Y1162 in FG pancreatic carcinoma cell line lysate. FG pancreatic carcinoma cells treated with or without EGF (50ng/ml) for 15 min Phospho-HER4-Y1162 Antibody was used at 1:750 in 3% BSA. Data and protocol kindly provided by Dr. Weis of Cheresh Lab, UCSD.)

Immunohistochemistry (IHC)

(Formalin-fixed and paraffin-embedded human cancer tissue reacted with the primary antibody, which was peroxidase-conjugated to the secondary antibody, followed by AEC staining. This data demonstrates the use of this antibody for immunohistochemistry; clinical relevance has not been evaluated. BC = breast carcinoma; HC = hepatocarcinoma.)

Immunofluorescence (IF)

(Confocal immunofluorescent analysis of Phospho-HER4-Y1162 Antibody with MCF-7 cell followed by Alexa Fluor 488-conjugated goat anti-rabbit lgG (green). Actin filaments have been labeled with Alexa Fluor 555 phalloidin (red).DAPI was used to stain the cell nuclear (blue).)

Uniprot Description

HER4: a receptor tyrosine kinase of the EGFR family. Specifically binds and is activated by neuregulins, NRG- 2, NRG-3, heparin-binding EGF-like growth factor, betacellulin and NTAK. Heterodimerizes and signals with other EGF receptors. Interaction with these factors induces cell differentiation. Not activated by EGF, TGF-A, and amphiregulin. Interacts with PDZ domains of DLG2, DLG3, DLG4 and the syntrophin SNTB2. Interacts with WWOX. May act as a tumor suppressor: overexpressed in head and neck cancer , but downregulated in renal cancer, papillary carcinoma, high-grade gliomas and invasive breast cancer. 3 alternatively-spliced isoforms of the human protein have been reported.
