Anti-DNAJB11 antibody produced in rabbit

HPA010814    Human Protein Atlas characterization data

DNAJB11 (DnaJ (Hsp40) homolog, subfamily B, member 11) belongs to family of endoplasmic reticulum (ER) Hsp40/DnaJ family. It is a part of ERAD (Endoplasmic-reticulum-associated protein degradation), and is a heat shock protein 40 (HSP40) chaperone. It contains the J domain, which is a highly conserved region made of 75 amino acids. It also shares certain domains with other HSP40 chaperones. These domains include a C-terminal domain, a glycine/phenylalanine-rich putative linker region and a cystine-rich domain. It is a soluble glycoprotein, oriented towards the luminal region of endoplasmic reticulum (ER). DNAJB11 is expressed ubiquitously, and has the highest expression in secretory tissues.

Anti-DNAJB11 antibody is suitable for immunoprecipitation. Anti-DNAJB11 antibody produced in rabbit, a Prestige Antibody, is developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org). 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.

DNAJB11 (DnaJ (Hsp40) homolog, subfamily B, member 11) is a part of unassembled immunoglobulin (Ig) heavy chain:BiP (binding immunoglobulin protein) complex, where it acts as a co-factor for BiP, and helps in folding and assembly of proteins. It plays a major role in mammalian cell resistance to vero toxin. It is also involved in ER (endoplasmic reticulum) stress tolerance. It is secreted in the extracellular space, where it binds to mis-folded proteins and prevents their aggregation. It also reduces the toxicity of disease-related prion protein. DNAJB11 is involved in the intoxication pathway of cholera toxin.

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.
