Gene Information

human ... PPM2C(54704)

General description

The gene pyruvate dehydrogenase phosphatase catalytic subunit-1 (PDP1) is mapped to human chromosome 8q22.1. It belongs to protein phosphatase 2C (PP2C) family. PDP1 is highly expressed in skeletal muscles.


[Pyruvate dehydrogenase [acetyl-transferring]]-phosphatase 1, mitochondrial precursor recombinant protein epitope signature tag (PrEST)


All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org)and as a result, are supported by the most extensive characterization in the industry.

The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link.

Biochem/physiol Actions

Pyruvate dehydrogenase complex (PDC) is important for glucose homeostasis. The core of PDC consists of pyruvate dehydrogenase phosphatase catalytic subunit-1 (PDP1) and pyruvate dehydrogenase E1 component subunit-α (PDHA1). De-phosphorylation of pyruvate dehydrogenase by PDP1 is required for activating PDC. PDP1 is down-regulated in circulating lymphocytes of obese patients, signaling insulin resistance.

Features and Benefits

Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.

Every Prestige Antibody is tested in the following ways:
  • IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
  • Protein array of 364 human recombinant protein fragments.


Corresponding Antigen APREST73649.

Physical form

Solution in phosphate-buffered saline, pH 7.2, containing 40% glycerol and 0.02% sodium azide
