Carboxypeptidase A4 (CPA4), a zinc-containing exopeptidase, is secreted from a soluble proenzyme (pro-CPA4). It is a member of the family of Zn-containing metallocarboxypeptidases with a characteristic α/β-hydrolase fold. The CPA4 gene is mapped to human chromosome 7q32.2.
Carboxypeptidase A4 Precursor recombinant protein epitope signature tag (PrEST)
Anti-CPA4 antibody produced in rabbit has been used in immunohistochemistry and immunostaining (1:300).
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
Carboxypeptidase A4 (CPA4) catalyzes the release of carboxy-terminal amino acids. It regulates inflammation. An elevated expression of CPA4 is observed in esophageal, pancreatic, and lung tumors. It is implicated in prostate cancer aggressiveness.
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.
