The Role of SAMS Peptide in AMPK Assays

AMPK, often referred to as the "master regulator of cellular energy homeostasis," plays a crucial role in maintaining metabolic balance within cells and organismsAMP-Activated Protein Kinase in Human Liver Using .... Its activation signals a state of energy stress, prompting the cell to conserve energy by inhibiting ATP-consuming processes and promoting ATP-producing pathways. The SAMS peptide serves as an ideal substrate for these assays because it is specifically recognized and phosphorylated by AMPK. This targeted interaction allows for the quantification of AMPK activity by detecting the degree of SAMS peptide phosphorylation.

Unlike other potential substrates, the SAMS peptide exhibits a high degree of specificity for AMPK. Studies have shown that it is not readily phosphorylated by other purified protein kinases, ensuring that the observed phosphorylation is predominantly due to AMPK activitySAMS Peptide (CAS 125911-68-4). This specificity is crucial for obtaining accurate and reliable data in kinase assays, enabling researchers to confidently assess the impact of various experimental conditions or compounds on AMPK function. The SAMS peptide's sequence is derived from acetyl-CoA carboxylase, a known target of AMPK, further solidifying its suitability for these studies.

Understanding AMPK and its Substrates

AMP-activated protein kinase exists in various forms across different species, including human and rat AMPKs. While the SAMS peptide is a well-established substrate, research has also explored other potential peptide substrates, such as the HMG peptide. Some studies suggest that certain AMPKs may exhibit a higher affinity for the HMG peptide compared to the SAMS peptide under specific experimental conditions. However, the SAMS peptide remains the most widely adopted and validated substrate for routine AMPK activity measurements due to its excellent specificity and ease of use in in vitro kinase assaysWARNING: This product is for research use only, not for human or veterinary use.SAMS peptide is a specific substrate for the AMP-activated protein kinase (AMPK) ....

The phosphorylation of the SAMS peptide by AMPK results in the formation of phospho-SAMS peptide, which can then be detected through various biochemical methods. This process provides a direct and sensitive measure of AMPK's enzymatic capacityEffects of pH and temperature on the K m for SAMS peptide of O. .... For instance, using SAMS peptide in an assay buffer allows for the direct measurement of AMPK activity by monitoring the rate at which the peptide becomes phosphorylated. This technique is fundamental for understanding how cellular signals, drug treatments, or genetic modifications influence AMPK's role in energy metabolism.SAMS Peptide | AMPK Substrates: Tocris Bioscience
