ERBB4 Antibody – Mouse Monoclonal

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.
