CC -!- FUNCTION: Negatively regulates class switch recombination or isotype
CC switching in splenic B-cells. {ECO:0000250|UniProtKB:Q68FF0}.
CC -!- SUBUNIT: Homodimer. Interacts (via the BTB domain) with HDAC1 and
CC NCOR2. {ECO:0000250|UniProtKB:Q68FF0}.
CC -!- ALTERNATIVE PRODUCTS:
CC Event=Alternative splicing; Named isoforms=4;
CC Name=1;
CC IsoId=Q6NSI8-1; Sequence=Displayed;
CC Name=2;
CC IsoId=Q6NSI8-2; Sequence=VSP_032302;

CC Name=4;
CC IsoId=Q6NSI8-4; Sequence=VSP_032300, VSP_032301;
CC -!- DOMAIN: The BTB domain is important for homodimerization and for its
CC function in negative regulation of class switch recombination.
CC {ECO:0000250|UniProtKB:Q68FF0}.
CC -!- SIMILARITY: Belongs to the KIAA1841 family. {ECO:0000305}.
CC -!- SEQUENCE CAUTION:
CC Sequence=BAB47470.1; Type=Erroneous initiation; Note=Extended N-terminus.; Evidence={ECO:0000305};
