Gene Information

human ... AHNAK(79026)

General description

The gene AHNAK (neuroblast differentiation-associated protein) is mapped to human chromosome 11q12.2. AHNAK is strongly expressed in muscular cells, for instance cardiomyocytes and skeletal muscle cells. The protein localizes at the plasma membrane, cytoplasm and nucleus.

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

AHNAK (neuroblast differentiation-associated protein) interacts with muscle membrane repair protein, dysferlin. It is recruited to the bacterial invasion site and is involved in type-3 secretion system mediated invasion of Salmonella and Chlamydia trachomatis. AHNAK is down-regulated in neuroblastoma cell line, small cell lung carcinomas and Burkitt lymphomas, whereas, up-regulated in prostate cancer cell line, breast cancer, fibrosarcoma and glioma.

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.

AHNAK, a large 629 kDa protein, has been implicated in membrane repair, and the annexin A2-S100A10 heterotetramer [(p11)(2)(AnxA2)(2))] has high affinity for several regions of its 1002-amino-acid C-terminal domain. (p11)(2)(AnxA2)(2) is often localized near the plasma membrane, and this C2-symmetric...
