Transcript elongation on a nucleoprotein template
Abstract
Chromatin forms a general, repeating barrier to elongation of transcripts by eukaryotic RNA polymerases. Recent studies of nucleosome structure and histone modifications reveal a set of likely mechanisms for control of elongation through chromatin. Genetic and biochemical studies of transcription have identified a set of accessory factors for transcript elongation by RNA polymerase II (Pol II) that appear to function in the context of chromatin. The C-terminal repeated domain (CTD) of Pol II may also play a role in regulating elongation through chromatin.
