Neuregulin/Heregulin is a family of related growth factors that are differentially spliced variants of four genes: NRG1, NRG2, NRG3 and NRG4. The longest forms of NRG contains several different modular domains and tissue-specific splicing results in many NRG isoforms containing different sets of these domains. Alternative splicing produces two types of EGF domain, designated a and b. HRG-Beta1 contains an Ig domain and an EGF domain necessary for direct binding to receptor tyrosine kinases erbB-3 and erbB-4. HRG-Beta1 binding causes erbB-3 and erbB-4 to dimerize with erbB-2 (Her2/neu) and thereby regulates the phosphorylation of erbB-2 tyrosines. HRG-Beta1 stimulates proliferation and motility of breast cancer cells and plays a role in wound healing by stimulating epidermal migration and differentiation of epidermal cells and by stimulating the expression of integrins in the epidermis.
