Informations sur le gène

human ... TOP2A(7153)

Description générale

The topoisomerase II A gene (TOP2A), with 35 exons and more number of class 0 introns spanning approximately 30kb, is mapped to human chromosome 17q12-q21 in close proximity to the human epidermal growth factor receptor 2 (HER2) oncogene. The gene codes for 170-kDa protein called DNA topoisomerase 2-α. TOP2A is expressed in the nucleoplasm of cells and is characterized with C-terminal domain and catalytic domain involved in dimerization or nuclear localization.

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.

Actions biochimiques/physiologiques

Topoisomerase II A (TOP2A) enzyme plays a vital role in DNA replication and cell proliferation. Experimental studies observed increased expression of this enzyme in chinese patients with gastric carcinoma. DNA topoisomerase 2-α acts as a target enzyme for an anthracycline drug called as epirubicin and many other antineoplastic drugs. Top2α is involved in reducing the topological stress in cells. The hsa-miR-485-3p downregulates the expression of nuclear transcription factor Y subunit β (NFYΒ), which acts as a mediator of Top2α. Consequently, it decreases the expression of Top2α and its drug responsiveness. Top2α enzyme plays an important role in maintenance of chromosome condensation and segregation. Ataxia telangiectasia mutated (ATM)-dependent regulation of TOP2A helps in TOP2 stability and also it is sensitive to TOP2 inhibitor.

Caractéristiques et avantages

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.
