Application

All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project 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. We also provide Prestige Antibodies® protocols and other useful information.

Biochem/physiol Actions

PNN (pinin, desmosome associated protein) is a 140kDa phosphoprotein which is present in desmosomes and nuclear speckles. It colocalizes with mRNA splicing factors in nuclear speckled domains and plays an important role in mRNA processing. It is involved in the regulation of cell-cell adhesion of corneal epithelial cells. It also interacts with transcriptional repressor and pre-mRNA processing machinery in the nucleus. It is associated with the desmosome-intermediate filament complex and may be involved in pinning the intermediate filaments to the desmosome. Pinin is also involved in the regulation of the activity of several tumor suppressor genes. Due to its dual localization, pinin acts as a moonlighting protein with more than one function.

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.

Pinin (PNN), a desmosome associated protein, was demonstrated to be over-expressed and act as a tumor-promoting factor in ovarian cancer, hepatocellular carcinoma and colorectal cancer. However, the precise role of PNN in prostate cancer is still unknown. In the study

Pnn/DRS protein is associated with desmosomes and colocalizes with splicing factors in nuclear speckled domains. The potential interaction of Pnn with RNPS1, a pre-mRNA splicing factor and a component of the exon-exon junction complex, prompted us to examine whether Pnn

Pre-mRNA splicing occurs in a large macromolecular RNA-protein complex called the spliceosome. The major components of the spliceosome include snRNP and SR proteins. We have previously identified an SR-like protein, pinin (pnn), which is localized not only in nuclear speckles

We have identified a protein named pinin that is associated with the mature desmosomes of the epithelia (Ouyang, P., and S.P. Sugrue. 1992. J. Cell Biol. 118:1477-1488). We suggest that the function of pinin is to pin intermediate filaments to

Pinin (Pnn/DRS/memA) plays an important role in regulating cell-cell adhesion of corneal epithelial cells. In the nucleus, Pnn interacts with both transcriptional repressor and pre-mRNA processing machinery. Here we investigated the consequences of "knocking down" Pnn expression with short hairpin
