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:
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.

DNA hypermethylation has emerged as a novel molecular biomarker for the evaluation of prostate cancer diagnosis and prognosis. Defining the specific gene hypermethylation profile for prostate cancer could involve groups of genes that specifically discriminate patients with indolent and aggressive

Active enkephalin and related peptide hormones or neurotransmitters are generated by proteolytic processing of inactive prohormone precursors. Little is known about the relative accessibilities of prohormone cleavage sites and conformations of subdomains that undergo proteolytic processing. Therefore, this study investigated
