IHC image of ab115321 staining in human skeletal muscle formalin fixed paraffin embedded tissue section, performed on a Leica BondTM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab115321, 5µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

Product details

PDH Kinases (PDKs) deactivate PDH by reversible phosphorylation. In humans and rodents, 4 PDK's are present in an organ-dependent manner. In all cases, PDK's are physically part of the PDH complex (binding via lipoyl domain 2 of E2), and they phosphorylate the E1 subunit at 3 specific serine residues. PDH phosphatases remove the phosphorylation and restore activity of PDH.

Supplementary information

Pan PDK or pyruvate dehydrogenase kinases are a family of enzymes that regulate glucose metabolism by inhibiting the pyruvate dehydrogenase complex (PDC). The four human PDK isoforms are known: PDK1 PDK2 PDK3 and PDK4. These kinases typically express in tissues like heart liver muscle and kidney where they play important roles in energy metabolism. The molecular weights of PDKs range from around 40 to 49 kDa.
Biological function summary

Pyruvate dehydrogenase kinases control the flux between glycolysis and the tricarboxylic acid cycle. By phosphorylating the E1α subunit of PDC PDKs decrease PDC activity slowing down the conversion of pyruvate into acetyl-CoA. In this way PDKs help balance energy production especially in tissues requiring flexible metabolic responses. This function connects them to energy homeostasis especially during starvation and exercise where fatty acids serve as the primary energy source.

Pathways

PDKs are central in key metabolic pathways like glycolysis and the tricarboxylic acid cycle. These pathways ensure energy production efficiency based on cellular needs. Through their action PDKs interact with proteins like the E2 and E3 components of PDC modifying their activities according to cellular conditions. The regulation of PDKs also involves signaling pathways affecting glucose and fat metabolism which makes them integral to broader metabolic control mechanisms.

Imbalances in PDK activity link to metabolic syndromes such as diabetes and cancer. In diabetes altered PDK expression can contribute to impaired glucose utilization impacting insulin sensitivity. In some cancers upregulated PDKs promote aerobic glycolysis known as the Warburg effect supporting rapid tumor growth. Proteins involved in insulin signaling pathways and oncogenes are often connected to PDKs in these contexts highlighting their role in disease progression and potential as therapeutic targets.

Target data

Kinase that plays a key role in regulation of glucose and fatty acid metabolism and homeostasis via phosphorylation of the pyruvate dehydrogenase subunits PDHA1 and PDHA2 (PubMed : 7499431, PubMed : 18541534, PubMed : 22195962, PubMed : 26942675, PubMed : 17683942). This inhibits pyruvate dehydrogenase activity, and thereby regulates metabolite flux through the tricarboxylic acid cycle, down-regulates aerobic respiration and inhibits the formation of acetyl-coenzyme A from pyruvate (PubMed : 18541534, PubMed : 22195962, PubMed : 26942675). Plays an important role in cellular responses to hypoxia and is important for cell proliferation under hypoxia (PubMed : 18541534, PubMed : 22195962, PubMed : 26942675).
