From Nucleosome Structure to Function (Karolin Luger)

In this episode of the Epigenetics Podcast, we caught up with Karolin Luger, Ph.D., from the University of Colorado in Boulder to talk about her work on solving the crystal structure of the nucleosome and on how histone chaperones like FACT act on chromatin.

During her postdoc with Timothy Richmond at the Swiss Federal Institute of Technology in Zürich, Karolin Luger was the first author on an all-time classic paper called "Crystal structure of the nucleosome core particle at 2.8 A resolution" which was published in Nature. This article was published more than 20 years ago now and it has been cited about 9000 times.

After completing her postdoc, she moved to Colorado to set up her own lab where she continued to work on the structure of the nucleosome and the factors that influence their structure. The most recent Nature paper published by her lab investigated how the FACT complex promotes both disassembly and reassembly of nucleosomes during gene transcription, DNA replication, and DNA repair.

In this interview, we discuss the efforts that went into solving the crystal structure of the nucleosome back in 1997, her work on histone chaperones, and her recent work on how FACT keeps nucleosomes intact after gene transcription.
