Counterregulation of chromatin deacetylation and histone deacetylase occupancy at the integrated promoter of human immunodeficiency virus type 1 (HIV-1) by the HIV-1 repressor YY1 and HIV-1 activator Tat.

Abstract excerpt

Repression of human immunodeficiency virus type 1 (HIV-1) transcription may contribute to the establishment or maintenance of proviral quiescence in infected CD4(+) cells. The host factors YY1 and LSF cooperatively recruit histone deacetylase 1 (HDAC1) to the HIV-1 long terminal repeat (LTR) and inhibit transcription. We demonstrate here regulation of occupancy of HDAC1 at a positioned nucleosome (nuc 1) near the...
