摘要： HDART binds with HDAC (histone deacetylase) and function as a repressor. HDART directly binds with Skip functioning as a transcription co-activator of a nuclear receptor to repress the transcription of the nuclear receptor. Moreover, HDART is one of transcription co-repressors of nuclear receptor, and binds with HDAC thereby enabling intense repression of transcription through the histone deacetylization of HDAC. On the other hand, a dominant negative peptide of HDART can be obtained, and it has been confirmed that this peptide activates transcription contrary to the HDART protein of the full length. Especially, the transcription activity of retinoic acid receptor with this peptide has an activity exceeding all-trans retinoic acid (ATRA).

摘要： An inhibitor of histone acetyltransferase p300 was isolated from human cDNA library and identified as a nuclear protein composed of 855 amino acid residues. It binds to the cysteine/histidine-rich region of p300, thereby inhibiting the transcriptional activation by p300. It also inhibits the transcription activity of p53, with p300 functioning as a coactivator, and inhibits the discontinuance of cell cycle that relies on p53.
摘要翻译：从人cDNA文库中分离组蛋白乙酰转移酶p300的抑制剂，鉴定为由855个氨基酸残基组成的核蛋白。它与p300的半胱氨酸/组氨酸富集区结合，从而抑制p300的转录激活。它还抑制p53的转录活性，p300作为共激活因子，并抑制依赖于p53的细胞周期的中断。
