Anti-PITX1 antibody produced in rabbit

PITX1 (paired-like homeodomain 1) is a homeodomain transcription factor related to bicoid. This gene is localized to human chromosome 5q31.1 and is expressed in hind limbs. It is also expressed in anterior pituitary, and is first expressed during early stages of development in Rathke′s pouch.

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.

PITX1 (paired-like homeodomain 1) is responsible for the development of hindlimbs in vertebrates. Mutations in this gene result in autosomal-dominant clubfoot malformation. Mutations also result in a wide range of lower limb malformations, including insufficiency of long bones and mirror-image polydactyly. This protein is down-regulated in lung and colorectal cancers and is involved in the development of pituitary gland. It functions as a tumor suppressor, and negatively regulates RAS (rat sarcoma) activity and TERT (telomerase reverse transcriptase) expression in melanoma cell lines. It controls the transcriptional response to hypoxia mediated by hypoxia inducible factor (HIF)α, and thus, might have potential as a therapeutic target in hypoxic cancers.

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.
