Transcription initiation in the context of chromatin
EMSL Project ID
50680
Abstract
The genetic information of eukaryotic cells is packaged into dense chromatin, which comes in the form of nucleosome arrays. Access to specific genomic sites requires that nucleosomes are remodeled to give access the replication, transcription and repair machinery. This process of nucleosome repositioning is a fundamental part of the transcription initiation process as the transcription start site where RNA polymerase II binds is blocked prior to gene activation. We seek to understand how the remodeling machinery binds and remodels this nucleosomes in the context of transcription initiation by reconstituting a chromatin remodeler with a modified nucleosome.
