The Geyer lab is interested in the regulation of transcription and the molecular mechanisms that govern immune receptor activation. We use a variety of techniques from molecular biology and biochemistry to structural biology to analyze interaction between proteins, RNA, lipids, and ligands. The transcription cycle is regulated by cyclin-dependent kinases that phosphorylate the RNA polymerase II. We analyze the transition from transcription initiation to productive elongation in eukaryotic cells. We study the molecular and structural mechanisms that determine the activity and regulation of transcription-controlling kinases, as well as their inhibition by small molecular compounds. We recently also focused on the analysis of receptor activation of NLRP3 and forma-tion of the NLRP3/ASC/caspase inflammasome. Besides NACHT-domain containing proteins, Toll-like receptors, RIG-I and the cGAS-STING pathway mediate the immune-recogni-tion of pathogens. We aim at identifying target sites in these immune regulators that allow for the specific interference with the immune system, e.g., by small molecular compounds.
