CC   -!- FUNCTION: Substrate recognition component of a DCX (DDB1-CUL4-X-box) E3
CC       protein ligase complex that mediates the ubiquitination and subsequent
CC       proteasomal degradation of target proteins. Has an essential role in
CC       mediating growth by negatively regulating insulin signaling. It also
CC       has a role in maintaining presynaptic function in the neuromuscular
CC       junction synapses of third-instar larvae.
CC       {ECO:0000250|UniProtKB:Q9VH36}.
CC   -!- PATHWAY: Protein modification; protein ubiquitination.
CC       {ECO:0000250|UniProtKB:Q96SW2}.
CC   -!- SUBUNIT: Likely a component of a DCX (DDB1-CUL4-X-box) protein ligase
CC       complex (By similarity). May interact with pic/DDB1 (By similarity).
CC       {ECO:0000250|UniProtKB:Q96SW2, ECO:0000250|UniProtKB:Q9VH36}.
CC   -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250|UniProtKB:Q9VH36}.
CC   -!- PTM: Ubiquitinated. {ECO:0000250|UniProtKB:Q9VH36}.
CC   -!- SIMILARITY: Belongs to the CRBN family. {ECO:0000305}.
