Stress-70 protein, mitochondrial precursor recombinant protein epitope signature tag (PrEST)


Anti-HSPA9B antibody produced in rabbit, a Prestige Antibody, is developed and validated by the Human Protein Atlas (HPA) project . Each antibody is tested by immunohistochemistry against hundreds of normal and disease tissues. These images can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. The antibodies are also tested using immunofluorescence and western blotting. To view these protocols and other useful information about Prestige Antibodies and the HPA, visit

Biochem/physiol Actions

Stress-70 protein, mitochondrial is a protein encoded by the HSPA9 gene in humans. It is a constitutive, new member of the hsp70 family. Localization mechanism of apoptin is tightly associated with HSPA9 overexpression. It plays an important role in cellular apoptosis both in tumor cell line (hepatoma carcinoma cell line (HepG2)) and normal cell line.

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.


Corresponding Antigen APREST77453.

Physical form

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

We have previously described peptide-binding proteins of 72 and 74 kDa (PBP72/74), which have been implicated as playing a role in antigen processing and are serologically related to the 70-kDa heat shock protein (hsp70) family. Here we report the cloning

Apoptin, a small protein derived from chicken anemia virus, possesses the capacity to specifically kill tumor cells while leaving normal cells intact. Previous studies have indicated that the subcellular localization of apoptin appears to be crucial for this tumor-selective activity.

Iron-sulfur (Fe-S) clusters are cofactors in hundreds of proteins involved in multiple cellular processes, including mitochondrial respiration, the maintenance of genome stability, ribosome biogenesis and translation. Fe-S cluster biogenesis is performed by multiple enzymes that are highly conserved throughout evolution

The iron-sulfur (Fe-S) cluster of the Rieske protein, UQCRFS1, is essential for Complex III (CIII) activity, though the mechanism for Fe-S cluster transfer has not previously been elucidated. Recent studies have shown that the co-chaperone HSC20, essential for Fe-S cluster

Our aim was to study the protein expression profiles of placenta obtained from lean and obese pregnant women with normal glucose tolerance at the time of term Caesarean section. We used two-dimensional difference gel electrophoresis (2D-DIGE), utilising narrow-range immobilised pH


Prestige Antibodies® Powered by Atlas Antibodies in Immunofluorescence Applications

One major rationale for investigating the subcellular location of a specific protein is that location is often tightly connected to function. For example, proteins locating to the nucleus are frequently implicated in gene regulation, proteins in mitochondria with energy production and Golgi-related proteins are often associated with protein modification and sorting.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
