MLC-Derived Peptide

KKRPQRRYSNVF is a myosin-light-chain-derived peptide used in protein-kinase studies associated with apoptosis and tumor-suppression research. The sequence contains a serine phosphoacceptor within a basic peptide context and has been used as a defined substrate in biochemical characterization of kinase activity. It is suitable for peptide phosphorylation assays and comparative kinase-substrate studies.

• protein kinase substrate assays
• serine phosphorylation studies
• apoptosis signaling research
• kinase substrate-specificity studies

The peptide is a defined biochemical substrate. It should not be described as an apoptosis-inducing peptide or tumor suppressor by itself; those terms refer to the associated kinase biology rather than an established intrinsic activity of this short peptide.
