CC -!- FUNCTION: Acts as a transcriptional repressor (PubMed:12741956).
CC Represses the promoter activity of the CDC25C gene stimulated by NFYA
CC (PubMed:12741956). May play a role in retinal development where it
CC regulates the composition of bipolar cell populations, by promoting
CC differentiation of bipolar OFF-type cells (By similarity). In the
CC brain, may promote maintenance and suppress differentiation of neural
CC progenitor cells in the developing cortex (By similarity).
CC {ECO:0000250|UniProtKB:Q8C0C0, ECO:0000269|PubMed:12741956}.
CC -!- SUBUNIT: Homodimer (via homeobox domain) (PubMed:12741956,
CC PubMed:14659886). Heterodimer with ZHX1 (via homeobox domain 1)
CC (PubMed:12741956). Heterodimer with ZHX3 (via homeobox domain 1)
CC (PubMed:12741956, PubMed:14659886). Heterodimerization with ZHX1 is not
CC necessary for repressor activity (PubMed:12741956). Interacts (via
CC homeobox domain) with NFYA (via N-terminus) (PubMed:12741956).
CC Interacts with EFNB1 intracellular domain peptide; the interaction
CC enhances ZHX2 transcriptional repression activity (By similarity).
CC {ECO:0000250|UniProtKB:Q8C0C0, ECO:0000269|PubMed:12741956,
