General description

PCK1 (phosphoenolpyruvate carboxykinase 1) is a widely expressed protein, and is expressed in multiple organs including brain. It is involved in gluconeogenesis in both liver and kidney. PCK1 gene codes for the cytoplasmic isoform of this enzyme. This gene is localized to human chromosome 20.

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

PCK1 (phosphoenolpyruvate carboxykinase 1) is a key element of gluconeogenesis, where it converts oxaloacetate to phosphoenolpyruvate. The PCK1 allele responsible for susceptibility to Alzheimer′s Disease (AD), is also responsible for increased brain atrophy in patients with multiple sclerosis. This enzyme plays an essential role in glyceroneogenesis and cataplerosis. Its expression is tightly controlled by glucagon and insulin, which act as activator and inhibitor respectively. Variants of this gene are also linked with susceptibility to type II diabetes (TIID).

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 APREST70474.
