Summaries for NRG3 Gene

Entrez Gene Summary for NRG3 Gene

  • This gene is a member of the neuregulin gene family. This gene family encodes ligands for the transmembrane tyrosine kinase receptors ERBB3 and ERBB4 - members of the epidermal growth factor receptor family. Ligand binding activates intracellular signaling cascades and the induction of cellular responses including proliferation, migration, differentiation, and survival or apoptosis. This gene encodes neuregulin 3 (NRG3). NRG3 has been shown to activate the tyrosine phosphorylation of its cognate receptor, ERBB4, and is thought to influence neuroblast proliferation, migration and differentiation by signalling through ERBB4. NRG3 also promotes mammary differentiation during embryogenesis. Linkage studies have implicated this gene as a susceptibility locus for schizophrenia and schizoaffective disorder. Alternative splicing results in multiple transcript variants encoding distinct isoforms. Additional transcript variants have been described but their biological validity has not been verified.[provided by RefSeq, Sep 2009]

GeneCards Summary for NRG3 Gene

NRG3 (Neuregulin 3) is a Protein Coding gene. Diseases associated with NRG3 include schizophrenia. Among its related pathways are PI-3K cascade and PI-3K cascade. GO annotations related to this gene include growth factor activity and transmembrane receptor protein tyrosine kinase activator activity. An important paralog of this gene is NRG1.

UniProtKB/Swiss-Prot for NRG3 Gene

  • Direct ligand for the ERBB4 tyrosine kinase receptor. Binding results in ligand-stimulated tyrosine phosphorylation and activation of the receptor. Does not bind to the EGF receptor, ERBB2 or ERBB3 receptors. May be a survival factor for oligodendrocytes.
