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

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.

Physical form

Solution in phosphate-buffered saline, pH 7.2, containing 40% glycerol and 0.02% sodium azide


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.

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.
