Structural highlights

Disease

CRBN_HUMAN Autosomal recessive nonsyndromic intellectual deficit;Distal monosomy 3p. The disease is caused by mutations affecting the gene represented in this entry.

Function

CRBN_HUMAN Component of some DCX (DDB1-CUL4-X-box) E3 protein ligase complex, a complex that mediates the ubiquitination and subsequent proteasomal degradation of target proteins and is required for limb outgrowth and expression of the fibroblast growth factor FGF8. In the complex, may act as a substrate receptor. Regulates 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.^{[1] [2]}
