Gene Information

human ... TPX2(22974)

General description

TPX2 (targeting protein for Xenopus kinesin-like protein 2) is a spindle assembly factor. It is a kinesin-like motor protein, which is directed toward the plus-end of microtubule. It localizes mainly to nucleus during interphase and has the highest level of expression during mitosis. This gene is localized to the human chromosomal locus 20q11.1. TPX2 protein has a molecular weight of 100kDa.

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

TPX2 (targeting protein for Xenopus kinesin-like protein 2) activates Aurora A and recruits it to spindles, and aids in spindle formation. This is achieved by the release of TPX2, during early mitosis, in a Ran-GTP dependent fashion. In mammals, it regulates the assembly of microtubules at kinetochores. This in turn is accomplished by the binding of microtubules to the COOH-terminal domain of Xenopus kinesin-like protein 2 (Xklp2). The expression of TPX2 is tightly regulated during different stages of cell cycle. Post cytokinesis, TPX2 levels decline rapidly, and remain as such through G1 phase. The expression levels increase again during S and G2 phase. This protein is also responsible for amplifying the response to DNA damage. TPX2 is implicated in the modulation of tumorigenesis in cervical cancer. It also plays a role in tumor growth and metastasis of human colon cancer.

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.
