CC -!- FUNCTION: Probable core component of cullin-based SCF-like E3
CC ubiquitin-protein ligase complexes which mediate the ubiquitination and
CC subsequent proteasomal degradation of target proteins (By similarity).
CC The E3 ubiquitin-protein ligase activity of the complex is dependent on
CC the neddylation of the cullin subunit (By similarity). Involved in ER-
CC Golgi transport by regulating the size of COPII coats, thereby playing
CC a key role in collagen export, which is required for embryonic stem
CC (ES) cells division (By similarity). May play a role in the regulation
CC of mittotic entry via ubiquitination of aurka (By similarity).
CC {ECO:0000250|UniProtKB:Q13618, ECO:0000250|UniProtKB:Q9JLV5}.
CC -!- PATHWAY: Protein modification; protein ubiquitination.
CC -!- SUBUNIT: Component of multiple BCR (BTB-CUL3-RBX1) E3 ubiquitin-protein
CC ligase complexes formed of cul3, rbx1 and a variable BTB domain-
CC containing protein acting as both, adapter to cullin and substrate
CC recognition subunit (By similarity). Interacts with btbd6
CC (PubMed:18855900). {ECO:0000250|UniProtKB:Q13618,
CC ECO:0000250|UniProtKB:Q9JLV5, ECO:0000269|PubMed:18855900}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250|UniProtKB:Q13618}.
CC -!- PTM: Neddylated. Attachment of NEDD8 is required for the E3 ubiquitin-
CC protein ligase activity of the SCF-like complex.
CC {ECO:0000250|UniProtKB:Q13618}.
CC -!- SIMILARITY: Belongs to the cullin family. {ECO:0000255|PROSITE-
CC ProRule:PRU00330}.
