ERBB4, also named as p180erbB4 and HER4, belongs to the protein kinase superfamily, Tyr protein kinase family and EGF receptor subfamily. ERBB4 specifically binds and it is activated by neuregulins, NRG-2, NRG-3, heparin-binding EGF-like growth factor, betacellulin and NTAK. Interaction with these factors induces cell differentiation. ERBB4 is not activated by EGF, TGF-A, and amphiregulin. ERBB4 catalyze the reaction: ATP + a [protein]-L-tyrosine = ADP + a [protein]-L-tyrosine phosphate. The antibody recognize the C-term of ERBB4. Alternatively spliced variants which encode different protein isoforms with calculated molecular weight of 144-147 kDa have been described. The apparent molecular weight of full-length ERBB4 is 150-200 kDa due to glycosylation and phosphorylation. Full-length ERBB4 can be cleaved into an 80-kDa ERBB4 intracellular fragment and a 120-kDa extracellular fragment (PMID: 11343971; 16251361).
