A novel nuclear receptor coactivator of transcription, p300 and CBP associated factor (p/CAF) has been shown to be required for estrogen, thyroid hormone, and retinoic acid-dependent gene expression. The histone acetyltransferase activity of p/CAF was demonstrated to play essential role in nuclear receptor dependent gene expression and it appeared to be transcription factor specific. The ligand-dependent association of p/CAF with nuclear receptor depends upon nuclear receptor corepressor (NCoR) dismissal. These data suggest that p/CAF complex plays a central role in nuclear receptor dependent gene regulation, a key element in steroid dependent cancer development.
