Peptide Name: ErbB3 (1325-1331) pY1328
Product Use: Services as a blocking peptide for use with the ErbB3-pY1328 rabbit polyclonal antibody (Cat. No.: AB-PK618) that is also available from Kinexus. This phosphopeptide may also be useful as a substrate for screening the phosphatase activity of protein phosphatases. The peptide sequence is located in the cytoplasmic region of ErbB3 near the C-terminus after the kinase catalytic domain. This is one of the major in vivo phosphorylation sites in ErbB3. Phosphorylation Phosphorylation induces interaction with Shc1.

Related Product 1: ErbB3 - pY1328 phosphosite-specific antibody (Cat. No.: AB-PK618) 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).
