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.
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.
