receptor tyrosine-protein kinase erbB-4; p180erbB4; tyrosine kinase-type cell surface receptor HER4 (ERBB4, HER4)

Function: - specifically binds & is activated by neuregulins, NRG-2, NRG-3, heparin-binding EGF-like growth factor, betacellulin & NTAK - interaction with ligand induces cell differentiation - ligand-binding increases Tyr phosphorylation - not activated by EGF, TGF-A, & amphiregulin - isoform JM-A is cleaved but not isoform JM-B is not - interacts with PDZ domains of DLG2, DLG3, DLG4 & the syntrophin SNTB2 - interacts with CBFA2T3, MUC1 & WWOX Structure: - homodimer or heterodimer with each of the other ERBB receptors (putative). - WW-binding motifs mediate interaction with WWOX - belongs to the protein kinase superfamily, Tyr protein kinase family, EGF receptor subfamily - contains 1 protein kinase domain Compartment: membrane Alternative splicing: named isoforms=3; JM-A, JM-B Expression: - expressed in brain, heart, kidney, skeletal muscle, parathyroid, cerebellum, pituitary, spleen, testis & breast > thymus, lung, salivary gland, & pancreas - isoform JM-A & isoform JM-B are expressed in cerebellum - only the isoform JM-B is expressed in the heart
