Gene Information

human ... NRG1(3084)

Biochem/physiol Actions

Growth factor ligand for ErbB3 and ErbB4 receptor tyrosine kinases. The binding of HRG results in receptor dimerization and receptor trans-autophosphorylation. The phosphorylated receptors recruit cellular signaling proteins, initiating signaling pathways.

Analysis Note

The biological activity is measured by its ability to stimulate the proliferation of human MCF-7 cells grown under serum-free conditions.
