Neuregulins (NRGs) are a multi member protein family involved in cell to cell communication. This family includes four human neuregulin paralogs NRG1-NRG4 which produce multiple isoforms through alternative splicing.
NRGs are involved in several physiological processes including heart and peripheral nervous system development. They act in part by binding to the extracellular region of ErbB/HER transmembrane tyrosine kinases, leading to receptor dimerization and ultimately to the activation of a complex network of downstream signaling events1,2.
NRG2 transcript levels markedly increase following birth, suggesting that NRG2 has important functions in the postnatal and adult brain. Several studies have also shown that NRG2 modulates glutamatergic transmission in GABAergic neurons and selectively affects GluN2B-containing NMDA receptors2,3.
The region containing the NRG2 locus is associated with schizophrenia and other psychiatric disorders and genetically linked to ADHD in genome-wide scans2.
