Gene Information

human ... RHBDD1(84236)

General description

The gene RHBDD1 (rhomboid domain containing 1) is a serine protease belonging to the Rhomboid family of proteins. The protein contains a rhomboid domain and is highly expressed in the testis. The gene is mapped to human chromosome 2q36.3.


Rhomboid domain-containing protein 1 recombinant protein epitope signature tag (PrEST)


Anti-RHBDD1 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.

Biochem/physiol Actions

The protein rhomboid domain containing 1 cleaves the Bcl-2 protein Bik, a proapoptotic member, and regulates Bik-mediated apoptotic pathway. It plays a crucial role in the progression of several cancers and may serve as a therapeutic target. It induces proteolysis of TSAP6 (tumor suppressor activated pathway-6), a multi-pass transmembrane protein, and regulates exosomal trafficking.

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 APREST72901.

Physical form

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