Protein Structure
UniProt Annotation
Function Substrate-specific adapter of a BCR (BTB-CUL3-RBX1) E3 ubiquitin-protein ligase complex required for efficient chromosome alignment and cytokinesis. The BCR(KLHL21) E3 ubiquitin ligase complex regulates localization of the chromosomal passenger complex (CPC) from chromosomes to the spindle midzone in anaphase and mediates the ubiquitination of AURKB. Ubiquitination of AURKB by BCR(KLHL21) E3 ubiquitin ligase complex may not lead to its degradation by the proteasome. {ECO:0000269PubMed:14528312, ECO:0000269PubMed:19995937}.
Subcellular Localization Cytoplasm, cytoskeleton, spindle {ECO:0000269PubMed:19995937}. Note=Localizes to the spindle midzone and targets CUL3 to this region.
