Biological Significance
Neuregulin/Heregulin is a family of structurally related polypeptide growth factors derived from alternatively spliced genes. To date, there are over 14 soluble and transmembrane proteins derived from the NRG1 gene. Proteolytic processing of the extracellular domain of the transmembrane NRG1 isoforms release soluble growth factors. HRG1 beta1 contains an Ig domain and an EGF-like domain that is necessary for direct binding to receptor tyrosine kinases erb3 and erb4. This binding induces erb3 and erb4 heterodimerization with erb2, stimulating intrinsic kinase activity, which leads to tyrosine phosphorylation.

Product Notes
The Heregulin beta 1 (Catalog #AAA5304505) is an Active Protein produced from Human and is intended for research purposes only. The product is available for immediate purchase. It is sometimes possible for the material contained within the vial of "Heregulin beta 1, Active Protein" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
