Function Direct ligand for ERBB3 and ERBB4 tyrosine kinase receptors. Concomitantly recruits ERBB1 and ERBB2 coreceptors, resulting in ligand-stimulated tyrosine phosphorylation and activation of the ERBB receptors. The multiple isoforms perform diverse functions such as inducing growth and differentiation of epithelial, glial, neuronal, and skeletal muscle cells; inducing expression of acetylcholine receptor in synaptic vesicles during the formation of the neuromuscular junction; stimulating lobuloalveolar budding and milk production in the mammary gland and inducing differentiation of mammary tumor cells; stimulating Schwann cell proliferation; implication in the development of the myocardium such as trabeculation of the developing heart. Binds to ERBB4 and ERBB3. Acts as a ligand for integrins and binds (via EGF domain) to integrins ITGAV
Subcellular Location Pro-neuregulin-1, membrane-bound isoform: Cell membrane, Single-pass type I membrane protein
Protein Families Neuregulin family
Tissue Specificity Widely expressed. Most tissues contain isoform alpha2A and isoform alpha2B. Isoform Alpha2 and isoform beta2 are the predominant forms in mesenchymal and non-neuronal organs. Isoform Beta1 is enriched in brain and spinal cord, but not in muscle and heart.
