OX NCBI_TaxID=9601;
RN [1]
RP NUCLEOTIDE SEQUENCE [LARGE SCALE MRNA].
RC TISSUE=Brain cortex;
RG The German cDNA consortium;
RL Submitted (NOV-2004) to the EMBL/GenBank/DDBJ databases.
CC -!- FUNCTION: Acts as a transcriptional repressor. Represses the promoter
CC activity of the CDC25C gene stimulated by NFYA. May play a role in
CC retinal development where it regulates the composition of bipolar cell
CC populations, by promoting differentiation of bipolar OFF-type cells. In
CC the brain, may promote maintenance and suppress differentiation of
CC neural progenitor cells in the developing cortex.
CC {ECO:0000250|UniProtKB:Q8C0C0, ECO:0000250|UniProtKB:Q9Y6X8}.
CC -!- SUBUNIT: Homodimer (via homeobox domain 1). Heterodimer with ZHX1 (via
CC homeobox domain 1). Heterodimer with ZHX3 (via homeobox domain 1).
CC Heterodimerization with ZHX1 is not necessary for repressor activity.
CC Interacts (via homeobox domain) with NFYA (via N-terminus). Interacts
CC with EFNB1 intracellular domain peptide; the interaction enhances ZHX2
CC transcriptional repression activity. {ECO:0000250|UniProtKB:Q8C0C0,
CC ECO:0000250|UniProtKB:Q9Y6X8}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000255|PROSITE-ProRule:PRU00108}.
CC Note=Colocalizes with EFNB1 intracellular domain in the nucleus.
CC {ECO:0000250|UniProtKB:Q8C0C0}.
CC -!- SIMILARITY: Belongs to the ZHX family. {ECO:0000305}.
