CC -!- FUNCTION: Substrate-specific adapter of a BCR (BTB-CUL3-RBX1) E3
CC ubiquitin ligase complex that acts as a regulator of neural crest
CC specification. The BCR(KBTBD8) complex acts by mediating
CC monoubiquitination of NOLC1 and TCOF1: monoubiquitination promotes the
CC formation of a NOLC1-TCOF1 complex that acts as a platform to connect
CC RNA polymerase I with enzymes responsible for ribosomal processing and
CC modification, leading to remodel the translational program of
CC differentiating cells in favor of neural crest specification.
CC {ECO:0000250|UniProtKB:Q8NFY9}.
CC -!- SUBUNIT: Component of the BCR(KBTBD8) E3 ubiquitin ligase complex, at
CC least composed of CUL3, KBTBD8 and RBX1.
CC {ECO:0000250|UniProtKB:Q8NFY9}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm, cytoskeleton, spindle
CC {ECO:0000250|UniProtKB:Q8NFY9}. Golgi apparatus
CC {ECO:0000250|UniProtKB:Q8NFY9}. Note=Translocates to the spindle
CC apparatus during mitosis. {ECO:0000250|UniProtKB:Q8NFY9}.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative splicing; Named isoforms=2;
CC Name=1;
CC IsoId=Q3UQV5-1; Sequence=Displayed;
CC Name=2;
CC IsoId=Q3UQV5-2; Sequence=VSP_023186;
CC -!- DEVELOPMENTAL STAGE: Down-regulated in differentiating embryonic stem
CC cells (ESCs). {ECO:0000269|PubMed:26399832}.
CC -!- SIMILARITY: Belongs to the KBTBD8 family. {ECO:0000305}.
