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}.
