Peptide Name: MEK3 (214-221) pS218
Product Use: Services as a blocking peptide for use with the MKK3-pS218 rabbit polyclonal antibody (Cat. No.: AB-PK713) 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 protein kinase catalytic domain activation T loop region between subdomains VII and VIII. S218 phosphorylation stimulates phosphotransferase activity.
Peptide Production Method: Solid-phase peptide synthesis
Peptide Origin: Homo sapiens
Peptide Sequence: YLVD-pS-VAK
Peptide Modifications N Terminus: Free amino
Peptide Modifications C Terminus: βAla-Cys

Scientific Background: MKK3 (MAP2K3, MEK3) is a Dual specificity protein kinase of the STE group and STE7 family. MKK3 is activated by cytokines and environmental stress in vivo. Phosphorylation of S218 and T222 increases its phosphotransferase activity. S218A and T222A substitutions are involved in inactivation. S218E and T222E mutations are associated in constitutive activation. It catalyzes the concomitant phosphorylation of a threonine and a tyrosine residue in the activation T loops of the p38 MAP kinase isoforms. Defects in the MKK3 gene may be involved colon cancer.
