ErbB3, Phosphorylated (Y1262) (ERBB3, v-erb-b2 Erythroblastic Leukemia Viral Oncogene Homolog 3 avian, HGNC:3431, ErbB-3, HER3, MDA-BF-1, c-erbB-3, c-erbB3, erbB3-S, p180-ErbB3, p45-sErbB3)

ErbB3 (also known as HER3) is a type I transmembrane growth factor receptor and member of the human epidermal growth factor receptor (HER) family. ErbB3 is unique among HER family members in that it contains a defective kinase domain, and is therefore active only as a partner in a heterodimer complex with other ErbBs. Despite ErbB3's lack of intrinsic kinase activity, these heterodimers can be quite potent: the ErbB2/ErbB3 complex is considered the most active ErbB signaling dimer for the activation of downstream pathways. In addition, monomeric ErbB3 serves as a low affinity receptor for the heregulins (HRG), while ErbB2/ErbB3 heterodimers form a high affinity receptor complex. Phosphorylation of ErbB3 at Y1262 following ligand binding generates a binding site for the Grb2 adaptor protein.\n\nApplications: \nSuitable for use in Western Blot.
