Introduction to AMPK signaling pathway

Based on Luminex technology platform, Creative Proteomics provides analysis services for key targets of AMPK signaling pathway.

AMP-activated protein kinase (AMPK) signaling pathway, a fuel sensor and regulator, promotes ATP-producing and inhibits ATP-consuming pathways in various tissues. AMPK is exists as a heterotrimeric complex composed of a catalytic α subunit and regulatory β and γ subunits.

Binding of AMP to the γ subunit allosterically activates the complex, making it a more attractive substrate for its major upstream AMPK kinase, LKB1. In response to low ATP levels, AMPK activation promotes signaling pathways that generate more ATP, including fatty acid oxidation and autophagy, and inhibits anabolic ATP-consuming processes including gluconeogenesis, lipid and protein synthesis. When nutrients are scarce, AMPK also acts as a metabolic checkpoint inhibiting cellular growth. For example, activation of AMPK enhances both the transcription and translocation of GLUT4, resulting in an increase in insulin-stimulated glucose uptake. In addition, it also stimulates catabolic processes such as fatty acid oxidation and glycolysis via inhibition of ACC and activation of PFK2.

AMPK Signaling Pathway Detection Service

AMPK negatively regulates several proteins central to ATP consuming processes such as TORC2, glycogen synthase, SREBP-1 and TSC2, resulting in the downregulation or inhibition of gluconeogenesis, glycogen, lipid and protein synthesis. Due to its role as a central regulator of both lipid and glucose metabolism, AMPK is considered to be a key therapeutic target for the treatment of obesity, type II diabetes mellitus, and cancer.

AMPK is a central regulator of cellular energy homeostasis, playing critical roles in regulating growth and reprogramming metabolism as well as in cellular processes including autophagy and cell polarity. The kinase is activated in response to stresses that deplete ATP supplies such as low glucose, hypoxia, ischemia, and heat shock. AMPK activation works through direct phosphorylation of multiple enzymes directly involved in these processes as well as through transcriptional control of metabolism by phosphorylating transcription factors, co-activators, and co-repressors.

Technology platform

We provide Luminex technology for AMPK signaling pathway analysis.

Luminex technology is a multifunctional liquid phase analysis platform developed on the basis of colored microspheres, laser technology, applied fluidics and high-speed digital signal processing technology. The core is to encode polypropylene microspheres or magnetic microspheres with fluorescent dyes. By adjusting the different ratios of the two fluorescent dyes, up to 100 microspheres with different fluorescence spectra can be obtained. Each kind of microspheres is covalently cross-linked. Capture antibodies against specific antigens.

AMP-activated protein kinase (AMPK) is a central regulator of cell energy homeostasis and plays a key role in regulating growth and reprogramming metabolism and cellular processes including autophagy and cell polarity.

In addition to Luminex Multiplex Assay, Enzyme-linked immunosorbent assay (ELISA), Flow cytometry (FACS analysis) technology can also be provided to meet other customer needs.
