General description
Truncated human sequence (amino acids 178-241) corresponding to the EGF domain and purified as a GST-fusion protein, cleaved with thrombin.
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.
Physical form
Solution in phosphate buffered saline containing 30% glycerol.
Analysis Note
Stimulates tyrosine phosphorylation of the ErbB-3/HER-3 receptor.
The biological activity is measured by its ability to activate the c-ErbB3/HER-3 receptor in treated MCF-7 cells.
