Product Number: PE-04AUL01
Peptide Name: Frk (384-390) pY387
Product Use: This phosphopeptide may be useful as a substrate for screening the phosphatase activity of protein phosphatases. The peptide sequence is located in the protein kinase catalytic domain activation T loop region between subdomains VII and VIII. Y387 phosphorylation is predicted to be stimulatory for phosphotransferase activity.

Scientific Background: Frk is a protein-tyrosine kinase of the TK group and Src family that is found in the nucleus.. It is involved in positive regulation of PTEN by increasing its stability and preventing degradation and negative regulation of cell proliferation. It may also have functions during G1 and S phase in the nucleus to suppress growth. Frk may be a tumour suppressor protein (TSP). Cancer-related mutations in human tumours point to a loss of function of the protein kinase. nsertional mutagenesis studies in mice support a role for this protein kinase in mouse cancer oncogenesis.
