Anti-TAF12 antibody produced in rabbit

General description

Transcription initiation factor TFIID subunit 12 (TAF12) is a TBP-associated factor (TAFs). It it a subunit of TFIID and SPT3-TAFII31-GCN5L acetylase (STAGA ) complexes. It contains a histone-fold domain (HFD) which possesses DNA binding capacity.

Immunogen

Transcription initiation factor TFIID subunit 12 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

Transcription initiation factor TFIID subunit 12 (TAF12) interacts with cyclic AMP-dependent transcription factor (ATF7), which is modulated by TBP-associated factor 4 (TAF4). It mediates the transcriptional activity of ATF7 where the N-terminal domain of ATF7 and the histone-fold domain (HFD) of TAF12 interact with each other to form a heterodimer. This increases the stability of the complex with the DNA. Along with the complex of TFIID and various other proteins, TAF12 mediates the regulation of RNA polymerase transcription. There is a formation of a nucleosome-like substructure within TFIID which has a tetramer of TAF6 and TAF9 along with homodimers of TAF12.

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.

Linkage

Corresponding Antigen APREST70900.

Physical form

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