Anti-MyBBP1A antibody produced in rabbit

HPA005466    Human Protein Atlas characterization data

Myb-binding protein 1a (MYBBP1A) is a transcriptional co-regulator, which was originally identified as the protein which interacts with the proto-oncogene c-Myb. It is largely localized to the nucleolus, as it contains basic amino-acid repeats at its C-terminal. This protein weighs 160kDa and is expressed ubiquitously. Processing of the C-terminal nucleolar signal peptide produces two N-terminal forms of 140kDa and 67kDa. These forms are found in the nucleoplasm. MYBBP1A is located in the chromosomal region 17p13.3.

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.

Myb-binding protein 1a (MYBBP1A) regulates essential functions such as cell division, proliferation and apoptosis. It binds to NFκB via its RelA/p65 subunit, and prevents it trans-activating capacity. It binds to multiple transcription factors, such as PPARγ co-activator 1α, and inhibits them. This protein also forms a part of the Ret-CoR co-repressor complex. It activates the aryl hydrocarbon receptor (AhR). It induces apoptosis by preventing Mdm2 mediated degradation of p53. MYBBP1A maintains the silent state of rDNA and negatively regulates the epigenetic state of silent rDNA. It also negatively regulates the expression of rRNA. MYBBP1A prevents breast cancer tumorigenesis and controls the metastasis as well as proliferation of head and neck squamous cell carcinoma cells.

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.

Corresponding Antigen APREST86952.

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