Gene Information

human ... PENK(5179)

General description

Proenkephalin-A precursor (PENK) is the prohormone precursor. The gene encoding it is localized on human chromosome 8q23-q24.

Immunogen

Proenkephalin A precursor recombinant protein epitope signature tag (PrEST)

Application

Anti-PENK antibody produced in rabbit, a Prestige Antibody, is developed and validated by the Human Protein Atlas (HPA) project . Each antibody is tested by immunohistochemistry against hundreds of normal and disease tissues. These images can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. The antibodies are also tested using immunofluorescence and western blotting. To view these protocols and other useful information about Prestige Antibodies and the HPA, visit sigma.com/prestige.

Biochem/physiol Actions

Opioid peptides are derived from the genes encoding precursors like proenkephalin-A (PENK). It is processed at 12 cleavage sites to give rise to enkephalin peptides. These peptides take part in controlling learning and memory, analgesia and other brain-regulated behaviors. The gene is shown to be hypermethylated in prostate cancer and thus may be of use as a molecular marker for prostate cancer diagnosis.

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.

Tumors are highly heterogeneous, and within their parenchyma, a small population of tumor-stem cells possessing differentiation potential, high oncogenicity, and self-renewal capabilities exists. These cells are pivotal in mediating tumor development, chemotherapy resistance, and recurrence. Ovarian cancer shares characteristics with
