Protein Structure
UniProt Annotation
Function 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. {ECO:0000269PubMed:18414909, ECO:0000269PubMed:20223979}.
Subcellular Localization Cytoplasm {ECO:0000269PubMed:20223979}. Nucleus {ECO:0000269PubMed:20223979}. Membrane {ECO:0000250}; Peripheral membrane protein {ECO:0000250}.
Disease Associations Mental retardation, autosomal recessive 2A (MRT2A) [MIM:607417]: A disorder characterized by significantly below average general intellectual functioning associated with impairments in adaptive behavior and manifested during the developmental period. Non-syndromic mental retardation patients do not manifest other clinical signs. MRT2A patients display mild mental retardation with a standard IQ ranged from 50 to 70. IQ scores are lower in males than females. Developmental milestones are mildly delayed. There are no dysmorphic or autistic features. {ECO:0000269PubMed:15557513}. Note=The disease is caused by mutations affecting the gene represented in this entry.
Tissue Specificity Widely expressed. Highly expressed in brain. {ECO:0000269PubMed:15557513, ECO:0000269PubMed:17380424}.
