Introduction
Neuregulin-4 (NRG4) is a part of the neuregulin family that owns 1 EGF-like domain and is a low affinity ligand for the ERBB4 tyrosine kinase receptor. NRG4 links ERBB1 and ERBB2 coreceptors, resulting in ligand-stimulated tyrosine phosphorylation and activation of the ERBB receptors.
Description
NRG4 Human Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 84 amino acids (1-61 a.a.) and having a molecular mass of 9.1kDa. NRG4 is fused to a 23 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques.
Source
