Neuregulin 1 or NRG1 is one of four proteins in the neuregulin family that act on the EGFR family of receptors. This growth factor was originally identified as a 44-kD glycoprotein that interacts with the NEU / ERBB2 receptor tyrosine kinase to increase its phosphorylation on tyrosine residues. NRG1 is a trophic factor that has been implicated in neural development, neurotransmission, and synaptic plasticity. NRG1 has multiple isoforms that are generated by the usage of different promoters and alternative splicing of a single gene. Neuregulin 1 (NRG1) is essential for the development and function of multiple organ systems, and its dysregulation has been linked to diseases such as cancer and schizophrenia. NRG1 is a schizophrenia candidate gene and plays an important role in brain development and neural function. Schizophrenia is a complex disorder, with etiology likely due to epistasis.
Post-translational: Proteolytic cleavage close to the plasma membrane on the external face leads to the release of the soluble growth factor form.N- and O-glycosylated. Extensive glycosylation precedes the proteolytic cleavage (By similarity).

Recombinant Human NRG1-beta 2/HRG1-beta 2 Protein (rp222178) - Protein Bioactivity
Measured in a serum-free cell proliferation assay using MCF‑7 human breast cancer cells. The ED50 for this effect is 0.01 ng/mL.
Recombinant Human NRG1-beta 2/HRG1-beta 2 Protein (rp222178) - SDS-PAGE
3 μg/lane of Recombinant Human NRG1-beta 2/HRG1-beta 2 Protein was resolved with SDS-PAGE under reducing (R) and non-reducing (N) conditions and visualized by Coomassie® Blue staining, showing the bands at 7.0 kDa under reducing conditions and 10.6 & 15.5 kDa under non-reducing conditions.
The NRG1-beta 2/HRG1-beta 2 is a class of EGF-like signaling molecules. Its domain is rich in cysteine residues and disulfide bonds, potentially facilitating disulfide bond formation (Uniprot ID: Q02297-7).
