抗-WTAP 兔抗

HPA010549    Human Protein Atlas characterization data

WTAP (Wilms tumor 1 associated protein) is a highly conserved protein that functions as an interaction partner of WT1 protein, and acts as a switch. It is exclusively localized to the nucleus, and was first recognized in a kidney cell line, as a WT1-associated protein. It has a molecular weight of 20kDa.

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.

WTAP (Wilms tumor 1 associated protein), along with WT1, controls the balance between quiescence and proliferation. It functions as an oncogene in gliomas and acute myeloid leukemia. It negatively controls the proliferation of vascular smooth muscle cells (SMCs), where its expression is elevated as SMCs achieve replicative quiescence. This protein is up-regulated in cholangiocarcinoma, where it is responsible for the control of migration and invasiveness. This protein controls the activity of EGFR (epidermal growth factor), and is up-regulated in glioblastomas, where it controls the migration and invasion.

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.
