Anti-HSF1 antibody produced in rabbit

General description

HSF1 (heat shock transcription factor 1) is a transcriptional protein, which plays an essential role in the heat shock process. It is a multi-domain protein, which is composed of a helix winged-loop helix DNA binding domain (DBD) in its N-terminal, three leucine zipper domains (LZ1-3), a core regulatory domain, another leucine zipper domain (LZ4), and a C-terminal transcription activation domain.

Immunogen

Heat shock factor protein 1 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

HSF1 (heat shock transcription factor 1) is capable of controlling the transcription of other genes. It mediates the expression of chaperone proteins, and increases cell survival under thermal stress. It regulates protein homeostasis, thus, determining ageing and longevity. It also functions as a transcription regulator of dystrophin protein, Dp71. This protein is over-expressed in hepatocellular carcinoma (HCC), and thus, has potential as a prognostic marker as well as a therapeutic target in the same. This protein is activated in CAFs (cancer associated fibroblasts), where it promotes maliganancy. Thus, high stromal expression of HSF1 protein in early-stage lung and breast is linked with poor patient prognosis.

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 APREST71034.

Physical form

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