Descripción

General description

Musculoaponeurotic fibrosarcoma oncogene homolog B (MafB) is a transcription factor which is present in a wide variety of tissues and has 311 amino acids containing a typical bZip motif in its carboxy-terminal region.

Immunogen

Transcription factor MafB 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.

Applications in which this antibody has been used successfully, and the associated peer-reviewed papers, are given below.

Biochem/physiol Actions

Musculoaponeurotic fibrosarcoma oncogene homolog B (MafB) forms a homodimer through its leucine repeat structure and specifically binds to Maf-recognition elements (MAREs). It forms heterodimers with v-Maf and Fos through its zipper structure and acts as a transactivator for a promoter linked to MAREs. Through formation of numerous bZip dimers, MafB along with the AP-1 components provide great diversity in transcriptional regulation for a wide variety of genes. MafB is specifically expressed in myelomonocytic cells and binds to the DNA-binding domain of v-ets avian erythroblastosis virus E26 oncogene homolog 1 (Ets-1) by its leucine–zipper domain. It also represses Ets-1 transactivation of promoters containing Ets binding sites and inhibits Ets-1–mediated transactivation of the transferrin receptor, which is known to be essential for erythroid differentiation. Overexpression of MafB in an erythroblast cell line down-regulates the endogenous transferrin receptor gene and inhibits differentiation without affecting cell proliferation.

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.
