Zusammenfassung der Projektergebnisse

After 6 years of experimental investigations within this Koselleck project, we could make substantial progress on every aspect of the Koselleck project initially described in the proposal. As anticipated, Chaetomium thermophilum ribosome biogenesis factors turned out to have in many aspects excellent properties for this type of research. Currently, many follow-up projects are going on in the laboratory, all based on findings derived from the Koselleck project.
