function:May act as transcription activator that binds DNA elements with the sequence 5'-CCCTATCGATCGATCTCTACCT-3' (By similarity). Repressor of ligand-dependent transcription activation by target nuclear receptors. Repressor of ligand-dependent transcription activation by ESR1, ESR2, NR3C1, PGR, RARA, RARB, RARG, RXRA and VDR.,similarity:Contains 1 HTH psq-type DNA-binding domain.,subunit:Interacts with ESR1 and ESR2 in the presence of estradiol. Interacts with CTBP1, HDAC3 and HDAC6. Component of a large corepressor complex that contains about 20 proteins, including CTBP1, CTBP2, HDAC1 and HDAC2.,tissue specificity:Ubiquitous.,
