Molecular Mechanisms of Chromatin Modifying Enzymes (Karim-Jean Armache)

Episode 92

January 25, 2023

In this episode of the Epigenetics Podcast, we caught up with Karim-Jean Armache from New York University - Grossman School of Medicine to talk about his work on the structural analysis of Polycomb Complex Proteins.

Karim-Jean Armache started his research career with the structural characterization of the 12-subunit RNA Polymerase II. After starting his own lab he used this knowledge in x-ray crystallography and electron microscopy to study how gene silencing complexes like the PRC complex act on chromatin and influence transcription. Further work in the Armache Lab focused on the Dot1, a histone H3K79 methyltransferase, and how it acts on chromatin, as well as how it is regulated by Histone-Histone crosstalk.
