WebJun 12, 2014 · In mammals, ChIP-seq studies of RNA polymerase II (PolII) occupancy have been performed to reveal how recruitment, initiation and pausing of PolII may control transcription rates, but the focus is rarely on obtaining finely resolved profiles that can portray the progression of PolII through sequential promoter states. ... RNA polymerase … WebJun 25, 2024 · FACT (facilitates chromatin transcription) is an evolutionarily conserved histone chaperone that was initially identified as an activity capable of promoting RNA polymerase II (Pol II) transcription through nucleosomes in vitro.In this report, we describe a global analysis of FACT function in Pol II transcription in Drosophila.We present …

Defining the Status of RNA Polymerase at Promoters
WebRNA polymerase II transcribes most eukaryotic genes that encode proteins. Recognition of the promoter and initiation of transcription by RNA polymerase II requires a number of general transcription factors.In addition, since many protein-encoding genes vary markedly in expression, a variety of specific transcription factors are needed for expression of … WebRecently, Rpb1 and Rpb2 subunits of RNA polymerase II (RNA Pol II) were shown to mediate RNA interference (RNAi)-directed chromatin modification but did not affect pre-siRNA levels. Here we show that another Pol II subunit, Rpb7 has a specific role in pre-siRNA transcription. We define a centromeric pre-siRNA promoter from which initiation is ...
