Scientific Background: ErbB3 (HER3) is a protein-tyrosine kinase of the TK group and EGFR family. It is a receptor kinase that bind and be activated by NTAK and neuregulins. It has been proposed to be deficient in phosphotransferase activity. While the kinase domain appararently lacks activity but heterodimerizes with other EGFRs permits transduction of growth signals. Phosphorylation of Y1222 and Y1260 induces interaction with PIK3C and PIK3R1. ErbB3 appears to be up-regulated in many cancer, including medulloblastomas, verrucous carcinomas, childhood medulloblastomas, carotid body tumours (CBT), and gestational trophoblastic tumours (GTD).
