General description

Heat shock protein-70 functions along with cochaperons, specifically J-domain proteins and nucleotide exchange factors (NEFs), which accelerate ATP hydrolysis and ADP-ATP exchange, respectively. The human cells express two mitochondrial NEF isoforms: Mitochondrial-GrpE protein homolog-1 (GRPEL1) and GRPEL2.

Immunogen

GrpE protein homolog 2, mitochondrial precursor 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

Mitochondrial-GrpE protein homolog-2 (GRPEL2) is up-regulated in active fibrovascular membranes. Using analytical ultracentrifugation and glutaraldehyde cross-linking GRPEL was shown to form dimer, which upon increasing protein concentration formed oligomers. The dimer can associate with DnaK and mitochondrial heat shock protein-70 (mtHSP70). mtHSP70 participates in protein folding, with help of GRPEL and mitochondrial DnaJ.

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.

In eubacteria and mitochondria, Hsp70 chaperone activity is controlled by the nucleotide exchange factor GrpE. We have identified the chloroplastic GrpE homolog of Chlamydomonas, CGE1, as an approximately 26-kD protein coimmunoprecipitating with the stromal HSP70B protein. When expressed in Escherichia
