Transcription Elongation Control by the Paf1 Complex (Karen Arndt)

<p>In this episode of the Epigenetics Podcast, we caught up with Karen Arndt from the University of Pittsburgh to talk about her work on transcription elongation control by the Paf1 complex.</p> <p>Karen Arndt and her lab investigate the process of transcriptional elongation and how RNA polymerase II overcomes obstacles like nucleosomes. One of the proteins that helps overcome those obstacles is the Paf1 complex. This complex associates with the transcribing polymerase and helps in modifying the chromatin template by ubiquitinating Histone H2B and methylating Histone H3.</p> <p class="md-end-block md-p"> </p> <p class="md-end-block md-p md-focus">References</p> <ul class="ul-list"><li class="md-list-item"> <p class="md-end-block md-p">Squazzo, S.
