RL Submitted (AUG-2006) to the EMBL/GenBank/DDBJ databases.
CC -!- FUNCTION: Acts as a transcriptional repressor. Increases DNMT3B-
CC mediated repressive transcriptional activity when DNMT3B is tethered to
CC DNA. May link molecule between DNMT3B and other co-repressor proteins
CC (By similarity). {ECO:0000250}.
CC -!- SUBUNIT: Forms homodimers. Heterodimer (via HD1 domain) with ZHX2 (via
CC HD1 domain). Also forms a heterodimer with ZHX3 which is a prerequisite
CC for repressor activity. Interacts with ATF7IP and NFYA. Interacts (via
CC homeobox domains) with DNMT3B (via PWWP domain) (By similarity).
CC {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Nucleus. Note=Colocalized in the nucleus with
CC DNMT3B. {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the ZHX family. {ECO:0000305}.
