H3K4me3, Set-Proteins, Isw1 and their Role in Transcription (Jane Mellor)

In this episode of the Epigenetics Podcast, we caught up with Jane Mellor from the University of Oxford to talk about her work on H3K4me3, SET proteins, Isw1 and their role in transcription.

Since the beginning of the century, Jane Mellor and her team have focused on H3K4 trimethylation and the factors that influence this mark. They discovered that H3K4me3 is an almost universal mark of the first nucleosome in every transcribed unit and all organisms. She could subsequently, together with the Kouzarides lab, identify SetD1, the enzyme that is responsible for writing this modification. Later on, the team characterized Isw1, a chromatin remodeler which “reads” H3K4me3. More recently the lab focuses on how the polymerase transcribes throughout the first nucleosomes of the transcribed region at the +2 nucleosome, with the help of Spt4.
