靶點(diǎn)詳情

功能：

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 (Probable). Normal degradation of key regulatory proteins is required for normal limb outgrowth and expression of the fibroblast growth factor FGF8. Maintains presynaptic glutamate release and consequently cognitive functions, such as memory and learning, by negatively regulating large-conductance calcium-activated potassium (BK) channels in excitatory neurons. Likely to function by regulating the assembly and neuronal surface expression of BK channels via its interaction with KCNT1. May also be involved in regulating anxiety-like behaviors via a BK channel-independent mechanism.

1. mitochondrially expressed CRBN exhibited protease activity, and was induced by oxidative stress. PMID: 27417535
2. We sequenced CRBN-thalidomide binding region in 38 thalidomide embryopathy individuals and 136 Brazilians without congenital anomalies, and performed in silico analyses. Eight variants were identified, seven intronic and one in 3'UTR. PMID: 27751757
3. These findings thus contribute to a growing list of ID disorders caused by CRBN mutations, broaden the spectrum of phenotypes attributable to Autosomal-recessive non-syndromic intellectual disability (ARNS-ID)and provide new insight into genotype-phenotype correlations between CRBN mutations and the aetiology of ARNS-ID. PMID: 28143899
4. CRBN expression is of prognostic value in MM patients ineligible for ASCT treated with thalidomide as an immunomodulatory drug. With low expression indicating a possible suboptimal treatment outcome, measurement of CRBN expression might serve as additional prognostic tool in the personalized treatment approach. PMID: 27618360
5. Plasmablast differentiation, whether induced by BAFF or CD40L, is prevented by modulation of CRBN activity with CC-220, which induces degradation of the B cell differentiation factors Aiolos and Ikaros. Downregulation of these B cell differentiation processes by CC-220 modulation of CRBN provides a new therapeutic approach to treating B cell-mediated pathology in SLE. PMID: 28848067

12. 45.2 of multiple myeloma patients were CRBN(+). Among patients treated with thalidomide-based regimens, CRBN(+) patients showed a better treatment response than did CRBN-negative patients. There was no significant difference in survival outcomes between thalidomide- and bortezomib-based regimens in CRBN(+) patients. PMID: 27365142
13. GS is acetylated at lysines 11 and 14, yielding a degron that is necessary and sufficient for binding and ubiquitylation by CRL4(CRBN) and degradation by the proteasome. PMID: 26990986
