Abstract

The process by which RNA polymerase II elongates RNA chains in vivo, where the template is at least partially in a nucleosomal configuration, remains poorly understood. To approach this question we have partially purified RNA polymerase II transcription complexes paused early in elongation. These complexes were then used as substrates for chromatin reconstitution. Elongation of the nascent RNA chains on these nucleosomal templates is severely inhibited relative to elongation on naked DNA templates. Elongation on the nucleosomal templates results in a reproducible template-specific pattern of transcripts generated by RNA polymerase pausing. The RNA polymerases are not terminated because the large majority will resume elongation upon the addition of Sarkosyl or 400 mM KCl. The effectiveness of RNA polymerase II pause/termination sites is enhanced by the presence of nucleosomes. For example, a pause site similar in sequence to the c-myc gene exon 1 terminator is used four to seven times more effectively in reconstituted templates. A comparison of elongation on templates bearing phased nucleosomes and on reconstituted templates that show no predominant phasing pattern indicates that the locations of pause sites are not related to the positions of the nucleosomes. Rather, the major determinant of RNA polymerase pausing on the nucleosomal templates appears to be the underlying DNA sequence.
