CC   -!- FUNCTION: Probable substrate-specific adapter of an E3 ubiquitin-
CC       protein ligase complex which mediates the ubiquitination and subsequent
CC       proteasomal degradation of target proteins (PubMed:14528312). Seems to
CC       regulate expression levels and/or subnuclear distribution of TOP1, via
CC       an unknown mechanism (By similarity). May play a role in mesenchymal
CC       differentiation where it promotes myogenic differentiation and
CC       suppresses adipogenesis (By similarity). {ECO:0000250|UniProtKB:P58544,
CC       ECO:0000269|PubMed:14528312}.
CC   -!- PATHWAY: Protein modification; protein ubiquitination.
CC   -!- SUBUNIT: Interacts (via C-terminus) with TOP1 (PubMed:11818025).
CC       Interacts with TRIM5 isoform Delta (PubMed:12878161). Interacts with
CC       CUL3 (PubMed:14528312). {ECO:0000269|PubMed:11818025,
