Biochem/physiol Actions

Growth factor ligand for ErbB3 and ErbB4 receptor tyrosine kinases.
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.
