Anti-MTA1 antibody produced in rabbit，100UL，HPA005544-100UL，Sigma

General description

Metastasis tumor antigen 1 (MTA1) is a part of the nucleosome remodeling and deacetylating (NuRD) complex, and is also a candidate member for the metastasis-associated family of genes. MTA1 is localized to chromosomal position 14q32.3. This protein is localized in the nucleus. It has a molecular weight of ~82kDa and consists of 715 amino acids. The C-terminus of MTA1 consists of a proline-rich region or the SH3 (SRC homology 3)-binding domain. It is also composed of a leucine zipper, a putative DNA-binding zinc finger motif and five SPXX motifs.

Immunogen

Metastasis-associated protein MTA1 recombinant protein epitope signature tag (PrEST)

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

Metastasis tumor antigen 1 (MTA1) is a gene related to the progression of cancer. Its expression is up-regulated in various cancers, such as liver, breast, ovarian and colorectal cancer. As a component of nucleosome remodeling and deacetylating (NuRD) complex, it is thought to play a role in transcription control and chromatin remodeling. It acts as a repressor of estrogen receptor α (ERα), and an activator of Breast Cancer Amplified Sequence 3 (BCAS3). BCAS3 gene is overexpressed in breast cancers, and hence, MTA1 might play a role in tumorigenesis of breast cancer. MTA1 activates paired box gene 5 (Pax5), which in turn is up-regulated in B-cell lymphomas. Hence, MTA1 might be involved in lymphogenesis. When up-regulated in cells, this protein leads to chromosomal instability and aberrant number of centrosomes. This is achieved by the suppression of BRCA1, which is a tumor suppressor gene.

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.
