Enables chemorepellent activity. Involved in ERBB4-ERBB4 signaling pathway and synapse assembly. Acts upstream of or within several processes, including intracellular signal transduction; mammary placode formation; and regulation of cell migration. Is active in extracellular space and glutamatergic synapse. Is expressed in several structures, including embryo mesenchyme; epidermis; mammary gland primordium; nervous system; and testis. Used to study schizophrenia. Orthologous to human NRG3 (neuregulin 3).
MGI Description
PHENOTYPE: Mutations in this gene result in abnormal, genetic background specific, mammary gland development. Male mice homozygous for a knock-out allele show novelty-induced hyperactivity, decreased prepulse inhibition, and impaired cued conditioning behavior.
