NRG1-beta 1, Human

NRG1-beta 1 Protein, a specific ligand for ERBB3, belongs to a family of structurally related polypeptide growth factors. NRG1-beta 1 Protein can regulate cell proliferation, differentiation, apoptosis and migration. NRG1-beta 1 Protein plays an important role in tumors and neurological diseases, and also has certain neuroprotective activity. NRG-1 Protein, Human is a recombinant NRG1-beta 1 protein expressed by E. coli without tags[1][2][3][4][5].
