| Target Function | Heregulin beta 1 (HRG-beta1), also named Neuregulin 1, plays a role in the development and function of the nervous system and heart. HRG-beta1 is also involved in the development and maintenance of synapses including the regulation of neurotransmitters and the branching morphogenesis of mammary glands. Signaling occurs with HRG-beta1 binding to either ErbB3 (Her3) or ErbB4 (Her4), which promotes recruitment of ErbB2 (Her2) and signal transduction through the MAPK and phosphatidylinositol-3 kinase (PI3K) pathways. |
| Tissue Specificity | HRG-beta1 expression has been identified in brain, spinal cord, neurons, glial cells, peripheral nerves, heart, mammary gland, skin, lungs, kidneys ovaries and testes. |
| Cellular Localization | Membrane-bound and cleaved soluble protein forms |
| Involvement In Disease | Dysregulation of HRG-beta1 is associated with cardiac hypertrophy, diabetic neuropathy, Charcot-Marie-Tooth disease, Alzheimer’s disease, multiple sclerosis (MS), metabolic syndrome, obesity, schizophrenia, and various cancers (breast, prostate, colorectal, non-small cell lung cancer (NSCLC), head and neck squamous cell carcinoma (HNSCC), and ovarian). |
