Neuregulin-1

A peptide factor originally identified by its ability to stimulate the phosphorylation the erbB-2 receptor (ERB-B2 RECEPTOR TYROSINE KINASES). It is a ligand for the erbB-3 receptor (RECEPTOR, ERBB-3) and the erbB-4 receptor. Variant forms of NEUREGULIN-1 occur through alternative splicing of its mRNA.
