A novel neuregulin isoform, termed gamma-HRG, was cloned and characterized from the human breast cancer cell line, MDA-MB-175. As observed with other neuregulins, gamma-HRG, is a product of alternative mRNA splicing of the neuregulin gene. Gamma-HRG contains the EGF-like and immunoglobulin-like doma...
