S6 Kinase Substrate Peptide

RRRLSSLRA is a basic serine-containing peptide used as a substrate for ribosomal S6 kinase-family activity measurements and studies of growth-factor-regulated phosphorylation.

• protein kinase activity assays
• kinase inhibitor screening
• signal-transduction research
• substrate-specificity studies

Exact sequence and terminal chemistry define assay behavior. Kinase substrates should be validated under the enzyme, ATP and buffer conditions used in the specific experimental system.
