Peptide Name: HGK (178-190) pT181+pT187

Product Use: This phosphopeptide may be useful as a substrate for screening the phosphatase activity of protein phosphatases. The presentation as a dimer increases the potential activity. The peptide sequence is located in the protein kinase catalytic domain activation T loop region between subdomains VII and VIII. T181 and T187 phosphorylation predicted to be stimulatory for phosphotransferase activity.

Scientific Background: ZC1 (HGK, MAP4K4) is a protein-serine/threonine kinase of the STE group and STE20 family. It may play a role in the response to environmental stress and cytokines such as TNF-alpha, and appears to act upstream of the JUN N-terminal pathway. ZC1 can phosphorylate SMAD1 at T322. Insertional mutagenesis studies in mice support a role for this protein kinase in mouse cancer oncogenesis.
