Gene Information

human ... CRBN(51185)

General description

The gene CRBN (cereblon) is mapped to human chromosome 3p26.2. It is strongly expressed in the brain. The encoded protein has a conserved Lon (ATP-dependent protease La) domain. The CRBN protein is present in the cytoplasm and nucleus.
CRBN protein interacts with:


cereblon recombinant protein epitope signature tag (PrEST)


All Prestige Antibodies®Powered by Atlas Antibodies 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.

Biochem/physiol Actions

CRBN (cereblon) mainly recruits substrates for E3 ubiquitin ligase. It interacts with BKCa (calcium-activated potassium channel subunit α-1), ClC-2 (chloride channel protein 2), AMPK (5′-AMP-activated protein kinase), PSMB4 (proteasome subunit β 4), ikaros (IKZF1), aiolos (IKZF3) and MEIS2 (Meis1-related protein). These interactions might be required for sending the proteins for ubiquitination by the E3 ubiquitin ligase. Degradation of IKZF1 (ikaros family zinc finger protein 1) and IKZF3 by lenalidomide (immunomodulatory drug)-bound CRBN helps in anti-myeloma effect of lenalidomide. Similarly, treatment with thalidomide in CRBN positive cells is effective in elderly patients with multiple myeloma. CRBN might also be associated with autosomal recessive nonsyndromic intellectual disability.

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 APREST79292.

Physical form

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

Proteolysis targeting chimeric molecule ARV 825 causes ubiquitination of bromodomains resulting in their efficient degradation by proteasome activity. Bromodomain degradation down-regulates MYC transcription contributing to growth inhibition of various human cancers. We examined the therapeutic potential of ARV 825 against...
