General description

Pyruvate dehydrogenase E1 component subunits alpha and beta, mitochondrial (EC 1.2.4.1; UniProt P08559 and P11177; also known as PDHE1-A type I and PDHE1-B, respectively) are encoded by the PDHA1 (also known as PDHA, PDHAD, PHE1A) and the PDHB (also known as PDHBD, PHE1B) genes (Gene ID 5160 and 5162, respectively) in human. The pyruvate dehydrogenase (PDH) complex catalyzes the overall, irreversible conversion of pyruvate to acetyl-CoA and CO2, and thereby links the glycolytic pathway to the tricarboxylic cycle. This complex contains multiple copies of three enzymatic components: PDH (E1 or PDHE1-A type I), dihydrolipoamide acetyltransferase (E2), and lipoamide dehydrogenase (E3). PDH (E1) performs the first two reactions within the PDH complex: a decarboxylation of pyruvate and a reductive acetylation of lipoic acid. Lipoic acid is covalently bound to dihydrolipoamide acetyltransferase (E2), which is the second catalytic component enzyme of PDC. The reaction catalyzed by PDH (E1) is considered to be the rate-limiting step for the PDH complex. PDH is regulated by both pyruvate dehydrogenase kinase (PDK)-mediated phosphorylation and feedback inhibition. Phosphorylation at Ser-232, Ser-293 and Ser-300 by PDK family kinases inactivates the enzyme; for this phosphorylation at a single site is sufficient. Dephosphorylation at all three sites, Ser-232, Ser-293, and Ser-300, is required for reactivation. PDH (E1) deficiency has been linked to primary lactic acidosis in children.

Specificity

This polyclonal antiserum detects both PDH alpha and beta subunits (Pliss, L., et al. (2004). Neurochem. 91(5):1082-1091).

Immunogen

Co-expressed recombinant full-length mature human PDH E1 alpha and beta subunits.

Application

Detect Pyruvate dehydrogenase E1 component subunit alpha, somatic form, mitochondrial using this rabbit polyclonal Anti-PDH, Cat. No. ABS2082, validated for use in Immunocytochemistry, Immunofluorescence, Immunohistochemistry, and Western Blotting.
Immunocytochemistry Analysis: A 1:300 dilution from a representative lot detected PDH immunoreactivity in 4% paraformaldehyde-fixed, 1% Triton X-100-permeabilized BE(2)C human neuroblastoma cells (Courtesy of Professor Mulchand S. Patel, Ph.D., SUNY Buffalo, NY, U.S.A).

Western Blotting Analysis: A 1:4,000 dilution from a representative lot detected endogenous PDH alpha and beta subunits in 50 µg of mouse liver tissue lysate as well as 50 ng of purified recombinant human PDH alpha and beta subunits (Courtesy of Professor Mulchand S. Patel, Ph.D., SUNY Buffalo, NY, U.S.A).

Immunofluorescence Analysis: A representative lot immunostained oocytes in Bouins fluid-fixed, paraffin-embedded sections of mouse ovaries. A loss of oocyte PDH immunostaining was observed in ovaries from transgenic mice carrying homozygous floxed Pdha1 alleles and zona pellucida protein-3 (Zp3) promoter-driven Cre expression to allow oocyte-specific Pdha1 deletion (Johnson, M.T., et al. (2007). Biol Reprod. 77(1):2-8)

Immunohistochemistry Analysis: A representative lot immunostained neural cells in paraplast-embedded brain microtome sections from Bouins fluid-perfused mice. A marked increase in cells with low PDH immunostaining was observed in brain from transgenic mice carrying heterozygous floxed Pdha1 allele and nestin promoter-driven Cre expression to allow brain tissue-specific Pdha1 deletion (Pliss, L., et al. (2004). Neurochem. 91(5):1082-1091).

Western Blotting Analysis: A representative lot detected reduced level of PDH alpha & beta subunits in brain, but not liver, tissue from transgenic mice carrying heterozygous floxed Pdha1 allele and nestin promoter-driven Cre expression to allow brain tissue-specific Pdha1 deletion (Pliss, L., et al. (2004). Neurochem. 91(5):1082-1091).
