Product Name: KHS1 (171-177) pS174
Product Number: PE-04AVU01
Peptide Name: KHS1 (171-177) pS174
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. S174 phosphorylation is stimulatory for phosphotransferase activity.

Peptide Origin: Homo sapiens
Peptide Sequence: KRK(pS)FIG
Peptide Modifications N Terminus: Free amino
Peptide Modifications C Terminus: Amide
Peptide Modifications Other: Phosphorylated
Storage Conditions: -20°C
Scientific Background: KHS1 (MAP4K5) is a protein-serine/threonine kinase of the STE group and STE20 family. It has been proposed to be upstream of the JUN N-terminal pathway and may respond to environmental stresses. A mutation in KHS1, K49R, inhibits the kinase phosphotransferase activity and inhibits downstream JNK proteins.
