General description
Pro-neuregulin-2, membrane-bound isoform (UniProt: P56974; also known as Pro-NRG2; Divergent of neuregulin 1; DON-1) is encoded by the Nrg2 gene in mouse species. NRG2 is a novel member of the neuregulin family. Neuregulins serve as multi-potent epidermal growth (EGF) - like factor that influence growth, differentiation, survival, and fate of several cell types. Most NRGs are synthesized as membrane precursors that are converted to signaling-competent soluble ErbB receptor ligands via shedding of their ectodomains by alpha- or beta secretases. NGR2 acts as a direct ligand for ErbB3 and ErbB4 tyrosine kinase receptors. Its highest expression is found in the brain and is found in granules and Purkinje cells in the cerebellum. NRG1 and NRG2 mediate distinct biological processes by acting at different sites in tissues and eliciting different biological responses in cells and NRG-2 is shown to stimulate different ErbB-receptor tyrosine-phosphorylation profiles from NRG-1. The neuregulin receptor ErbB4 is reported to be an important modulator of GABAergic interneurons and neural network synchronization. In cultured cortical interneurons NMDA receptors are reported to be target of NRG2/ErbB4 signaling and this signaling downregulates NMDARs selectively in GABAergic interneurons.
