靶點詳情

功能：

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. Isoform 10 may play a role in motor and sensory neuron development. Binds to ERBB4. Binds to ERBB3. Acts as a ligand for integrins and binds (via EGF domain) to integrins ITGAV:ITGB3 or ITGA6:ITGB4. Its binding to integrins and subsequent ternary complex formation with integrins and ERRB3 are essential for NRG1-ERBB signaling. Induces the phosphorylation and activation of MAPK3/ERK1, MAPK1/ERK2 and AKT1. Ligand-dependent ERBB4 endocytosis is essential for the NRG1-mediated activation of these kinases in neurons.

Also, further data demonstrate that NRG1 activates the antioxidant pathway by upregulating the expression of antioxidant enzymes through NRF2, thus modulating redox homeostasis in PTC. PMID: 29901070
7. Mesenchymal stem cell-drived paclitaxel resistance in ErbB2/ErbB3-coexpressing breast cancer cells could be attributed to upregulation of Survivin via paracrine effect of NRG-1/ErbB3/PI-3K/Akt signaling, as either specific knockdown expression of ErbB3, or blocking of downstream PI-3K/Akt signaling, or specific inhibition of Survivin can completely reverse this effect. PMID: 29715459
8. The data suggest a role for transcriptional regulation of NRG1 in the predisposition to papillary thyroid carcinoma. PMID: 29121253

Also, NRG1-ErbB4 signaling suppresses GluN2B phosphorylation by Src inhibition. GluN2B is closely related to synaptic activity and its regulation by the NRG1-ErbB4-Src signaling axis highlights the importance of NRG1-ErbB4 signaling in symptomatic epilepsy pathology.

21. we show that ErbB3 interacts with the ESCRT-0 subunit Hrs both in the presence and absence of heregulin. This indicates an ESCRT-mediated sorting of ErbB3 to late endosomes and lysosomes, and in line with this we show that impaired ESCRT function leads to an endosomal accumulation of ErbB3. PMID: 28867611
22. NRG1 genotype is associated with substance use. PMID: 27353026

In contrast, we detected a European-specific association of a low-frequency variant, rs80227144, in SEMA3.

A chromosomal aberration involving NRG1 produces gamma-heregulin. Translocation t(8;11) with TENM4. The translocation fuses the 5'-end of TENM4 to NRG1 (isoform 8). The product of this translocation was first thought to be an alternatively spliced isoform. Gamma-heregulin is a soluble activating ligand for the ERBB2-ERBB3 receptor complex and acts as an autocrine growth factor in a specific breast cancer cell line (MDA-MB-175). Not detected in breast carcinoma samples, including ductal, lobular, medullary, and mucinous histological types, neither in other breast cancer cell lines.
