Gene Information
human ... HSCB(150274)
General description
The gene HSCB (iron-sulfur cluster co-chaperone protein HscB, mitochondrial) is mapped to human chromosome 22q12.1. It is expressed in various tissues and is mainly present in the mitochondria. However, small amount of HSCB is also detected outside mitochondria. It contains a conserved amino-terminal J-domain and a less conserved carboxyl-terminal region. It is popularly known as HSC20 (Heat shock cognate 20).
Immunogen
Co-chaperone protein HscB, mitochondrial Precursor recombinant protein epitope signature tag (PrEST)
Application
Anti-HSCB 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 sigma.com/prestige.
Biochem/physiol Actions
In the biogenesis of iron-sulfur proteins, the final step of iron-sulfur protein assembly involves transfer of an iron-sulfur cluster from a cluster-donor to a cluster-acceptor protein. This process is mediated by a molecular chaperone from the Hsc70 (Heat shock cognate) family and a co-chaperone of the J-domain family. HSCB (Iron-sulfur cluster co-chaperone protein HscB, mitochondrial) is homolog of DnaJ type co-chaperones. It is required for mitochondrial iron-sulfur cluster (ISC) assembly. Depletion of HSCB reduces mitochondrial and cytosolic ISC-containing enzymes. On the other hand, overexpression of HSCB protects cells from oxidative stress. HSCB interacts with iron-sulfur cluster scaffold protein and mitochondrial HSP70 (Heat shock protein).
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:
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.
