ANTI-PNMA1 (C15-1448-281)

General description

PNMA1 (paraneoplastic Ma antigen 1) belongs to a new family of six members including, PNMA2, PNMA3, PNMA4 (also termed as MAP-1), PNMA5, PNMA6A. This is a family of “brain/testis” proteins which are linked with paraneoplastic neurological syndrome (PNS). This protein is primarily expressed in brain and adult testis. It was first identified as a marker in a cancer patient suffering from PNS. It localizes in the nuclei and nucleoli of neurons. This protein has a putative molecular weight of 36.8kDa, and is composed of 330 amino acids. It has multiple putative casein kinase II and protein kinase C (PKC) phosphorylation domains.

Immunogen

Paraneoplastic antigen Ma1 recombinant protein epitope signature tag (PrEST)

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

PNMA1 (paraneoplastic Ma antigen 1) is linked with paraneoplastic neurological syndrome (PNS), which is an autoimmune disorder, resulting from ectopic expression of onconeuronal proteins in tumors. It is up-regulated in pancreatic cancer, especially in pancreatic ductal adenocarcinoma (PDAC), where it aids in cell growth. Studies on murine model suggest that PNMA1 linked paraneoplastic CNS (central nervous system) neurological syndromes include an autoimmune T-cell functionality.

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.

Linkage

Corresponding Antigen APREST70380.

Physical form

Solution in phosphate-buffered saline, pH 7.2, containing 40% glycerol and 0.02% sodium azide
