Summaries for CRBN Gene

Entrez Gene Summary for CRBN Gene

  • This gene encodes a protein related to the Lon protease protein family. In rodents and other mammals this gene product is found in the cytoplasm localized with a calcium channel membrane protein, and is thought to play a role in brain development. Mutations in this gene are associated with autosomal recessive nonsyndromic mental retardation. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Mar 2010]

GeneCards Summary for CRBN Gene

CRBN (Cereblon) is a Protein Coding gene. Diseases associated with CRBN include mental retardation, autosomal recessive 2 and autosomal recessive non-syndromic intellectual disability. GO annotations related to this gene include ATP-dependent peptidase activity.

UniProtKB/Swiss-Prot for CRBN Gene

  • Substrate recognition component of a DCX (DDB1-CUL4-X-box) E3 protein ligase complex that mediates the ubiquitination and subsequent proteasomal degradation of target proteins, such as MEIS2. Normal degradation of key regulatory proteins is required for normal limb outgrowth and expression of the fibroblast growth factor FGF8. May play a role in memory and learning by regulating the assembly and neuronal surface expression of large-conductance calcium-activated potassium channels in brain regions involved in memory and learning via its interaction with KCNT1. Binding of pomalidomide and other thalidomide-related drugs changes the substrate specificity of the human protein, leading to decreased degradation of MEIS2 and other target proteins and increased degradation of MYC, IRF4, IKZF1 and IKZF3.

    Size:
    442 amino acids
    Molecular mass:
    50546 Da
    Quaternary structure:
    • Interacts with KCNT1 (By similarity). Component of a DCX (DDB1-CUL4-X-box) protein ligase complex, at least composed of CRBN, CUL4A, DDB1 and RBX1. Interacts directly with DDB1 (PubMed:25043012, PubMed:25108355). Interacts (in pomalidomide-bound form) with IKZF1 and IKZF3 (PubMed:24328678).
    Miscellaneous:
    • Thalidomide was widely prescribed to pregnant women in the late 1950s as a sedative and as treatment against morning sickness. Thalidomide was found to be teratogenic, causing multiple birth defects. Recently, thalidomide use has increased for the treatment of multiple myeloma and erythema nodosum leprosum, a painful complication of leprosy. Thalidomide binding leads to a change in substrate-specificity of the human DCX (DDB1-CUL4-X-box) E3 protein ligase complex, and this is probably the underlying cause of the teratogenic activity of thalidomide, possibly due to abnormal regulation of the BMP and FGF8 signaling pathways (PubMed:20223979). The thalidomide-induced change in substrate specificity leads to increased degradation of MYC, IRF4, IKZF1 and IKZF3, and this is probably the reason for the anti-proliferative and immunomodulatory effects of thalidomide and related drugs (PubMed:25108355). Thalidomide is also teratogenic in chicken and zebrafish, but not in mice.
