Antibody Type: Polyclonal
Antibody Host Species: Rabbit
Antibody Immunogen Source: Human PDK2 (PDHK2) sequence peptide Cat. No.: PE-01AZZ90
Antibody Immunogen Sequence: MRWVWALLKNASLAC
Antibody Immunogen Description: Corresponds to amino acid residues M1 to A14; N-terminus.
Production Method: The immunizing peptide was produced by solid phase synthesis on a multipep peptide synthesizer and purified by reverse-phase hplc chromatography. Purity was assessed by analytical hplc and the amino acid sequence confirmed by mass spectrometry analysis. This peptide was coupled to KLH prior to immunization into rabbits. New Zealand White rabbits were subcutaneously injected with KLH-coupled immunizing peptide every 4 weeks for 4 months. The sera from these animals was applied onto an agarose column to which the immunogen peptide was thio-linked. Antibody was eluted from the column with 0.1 M glycine, pH 2.5. Subsequently, the antibody solution was neutralized to pH 7.0 with saturated Tris.
Antibody Modification: Unconjugated. Contact KInexus if you are interest in having the antibody biotinylated or coupled with fluorescent dyes.

Scientific Background: PDHK2 (PDK2, pyruvate dehydrogenase kinase 2) is a 72-kDa mitochondrial protein-serine/threonine kinase of the Atypical group and PDHK family. It is an essential kinase in the regulation of fatty acid and glucose metabolism by phosphorylating and inactivating the enzyme pyruvate dehydrogenase (PDC). It phosphorylates the E1 component of the PDC, primarily at Ser-293, Ser-300, and Ser-232, leading to a down-regulation of its activity. It acts as a gatekeeper in the mitochondria, controlling the rate of carbohydrate oxidation and directing pyruvate away from the TCA cycle, which is essential for maintaining carbohydrate homeostasis. PDHK2 activity is regulated by metabolic factors like pyruvate, NAD+, NADH, CoA, and acetyl-CoA. It can be inhibited by low levels of hydrogen peroxide (H2O2), acting as a sensor for oxidative stress and potentially increasing PDC activity during high mitochondrial respiration. PDHK2 features specialized binding sites, including a unique pyruvate binding site and a site for the inner lipoyl-bearing domain (L2) of the dihydrolipoyl transacetylase (E2) component of the PDC. PDHK2 expression is implicated in diseases such as diabetes and cancer. Overexpression of PDHK2 contributes to the Warburg effect (increased glycolysis) in cancer cells.
