General description

The gene WRB (tryptophan-rich basic protein) is mapped to human chromosome 21q22.3. It is also popularly called as CHD5 (congenital heart disease 5 protein). WRB is widely expressed in adult and fetal tissues, with higher expression in the heart, brain, liver, skeletal muscle and pancreas. The protein is localized mainly in the nucleus. However, WRB has also been shown to associate with endoplasmic reticulum membrane.

Immunogen

Tryptophan-rich protein recombinant protein epitope signature tag (PrEST)

Application

Anti-WRB 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

Tryptophan-rich basic protein (WRB) interacts with ATPase ASNA1 (Arsenite-stimulated ATPase) and recruits it to the endoplasmic reticulum (ER) membrane, thereby mediating insertion of tail-anchored proteins into the ER membrane. In Xenopus loss of WRB affects cell movements associated with cardiac formation. WRB interacts with cardiac transcription factor Castor (CASZ1). CHD5-CASZ1 interaction is necessary for cardiac morphogenesis in Xenopus.

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.
