AKT/PKB/Rac – Protein Kinase Substrate CAS NO.324029-01-8

AKT/PKB/Rac – Protein Kinase Substrate (commonly known as AKTide-2T) is a high-purity synthetic peptide extensively used in cell signaling and kinase biology research. It is engineered to serve as a highly specific and sensitive substrate for AKT (also known as PKB or Rac) serine/threonine kinases, allowing researchers to accurately measure kinase activity in vitro. This peptide is an essential tool for scientists studying the PI3K/AKT/mTOR signaling pathway, which is pivotal in regulating cell growth, survival, metabolism, and apoptosis. Its consistent quality and defined phosphorylation characteristics make it ideal for academic laboratories, pharmaceutical R&D, and biotechnology companies engaged in kinase drug discovery, assay development, and signal transduction studies.

1.MECHANISM OF ACTION

This peptide functions by containing a conserved optimal phosphorylation motif recognized by AKT/PKB/Rac kinases, wherein the serine residue within its sequence is specifically phosphorylated by the active kinase in an ATP-dependent manner. Beyond serving as a phosphate acceptor, it acts as a competitive inhibitor against natural substrates like histone H2B, binding to the kinase's active site with high affinity to block endogenous substrate phosphorylation. This dual capability allows researchers to utilize the peptide both to quantify the enzymatic rate of AKT (via radiolabeled or fluorescent ATP consumption assays) and to probe the substrate specificity and inhibition constants of potential kinase inhibitors in biochemical screening platforms.

2.PRODUCT INDICATIONS

The product is indicated for laboratory research applications focusing on oncology, diabetes, immunology, and neuroscience, particularly where the PI3K/AKT pathway is a central regulatory mechanism. It is suitable for use in kinase activity assays, substrate specificity profiling, inhibitor screening campaigns, and mechanistic studies of AKT signaling in cellular lysates or purified systems. Researchers and technicians in drug discovery units utilize this peptide to validate hit compounds from high-throughput screenings, optimize assay conditions for preclinical studies, and characterize the kinetic parameters of novel AKT modulators, ensuring robust and reproducible data generation in non-clinical settings.

3.CLINICAL EFFICACY OF PRODUCT

As a specialized research reagent, this peptide is not administered to humans or animals therapeutically, yet its "efficacy" is demonstrated by its critical role in validating the preclinical efficacy of numerous AKT-targeted therapies currently in clinical trials. It provides a reliable and standardized readout for measuring how effectively a candidate drug can inhibit AKT kinase activity in vitro, thereby predicting its potential to disrupt pathological signaling in cancer and metabolic disorders. The peptide’s well-characterized kinetic values (Km and Ki) ensure that experimental results are quantitatively comparable across different studies, significantly de-risking the early-stage translation of kinase inhibitor leads into viable clinical candidates.
