1.MECHANISM OF ACTION
This peptide does not have enzymatic activity but functions as a specific molecular tool to study phosphorylation-mediated protein interactions. The phosphorylated tyrosine residue (pY185) within its sequence mimics the key activation loop phosphorylation event in MAP kinases (e.g., pT185/pY187 in ERK2).
- Antibody Validation: Serving as a critical positive control to test the specificity and sensitivity of phospho-specific antibodies directed against the activation loop of MAP kinases (e.g., anti-phospho-ERK1/2).
- Protein-Protein Interaction Studies: Used in pull-down assays, surface plasmon resonance (SPR), or microscale thermophoresis (MST) to study the binding affinity and kinetics of SH2 or PTB domain-containing proteins (e.g., Grb2, Shc) to the phosphorylated MAP kinase motif.
- Phosphatase Assays: Acting as a defined substrate to measure the activity of protein tyrosine phosphatases (PTPs) or dual-specificity phosphatases (DUSPs) that dephosphorylate and inactivate MAP kinases.
- Calibration Standard: Quantifying the amount of phosphorylated MAP kinase in samples when used as a standard in quantitative phosphoproteomic or targeted mass spectrometry assays.
2.PRODUCT INDICATIONS
- Research & Diagnostic Tool Efficacy: Its "efficacy" is defined by its ability to generate reliable, reproducible data in the applications listed above. It is essential for validating reagents used in both research and clinical pathology assays that measure phospho-MAPK as a biomarker.
- Biomarker Development Support: Phosphorylated MAP kinases (e.g., p-ERK) are important biomarkers in cancer and inflammatory diseases. This peptide is used to develop and validate diagnostic antibodies and assays that measure these biomarkers in patient tumor samples, influencing prognosis and treatment decisions.
