CC   -!- FUNCTION: Probable substrate-specific adapter of CUL3-containing E3
CC       ubiquitin-protein ligases which mediate the ubiquitination and
CC       subsequent proteasomal degradation of host target proteins.
CC   -!- SUBUNIT: Interacts (via BTB domain) with host CUL3. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Host cytoplasm {ECO:0000250}.
CC   -!- DOMAIN: The BTB domain is responsible for the interaction with CUL3
CC       while the Kelch repeat domains supposely serve to recruit the cellular
CC       substrates. {ECO:0000250}.
