topic

Ribosomes, the cellular factories for protein production, are among the most intricate and complex ribonucleoprotein (RNP)-assemblies in the cell. Their biogenesis is tightly regulated and requires the coordinated activity of many cellular processes and can therefore be considered as a well-suited model system to study mechanisms of biogenesis of RNP complexes. Synthesis of the majority of ribosomal RNAs in eukaryotes is executed by a highly specialized RNA polymerase, Pol I. Our major interests are to understand mechanisms and regulation of the RNA polymerase I transcription machinery and to study how rRNA synthesis is coupled to rRNA maturation and assembly of pre-ribosomes.

Our goals are to reconstitute transcription initiation, elongation and termination from a minimal transcription system, to understand the roles of single subunits of the transcription machinery and to compare features of Pol I transcription to other nuclear RNA polymerases.
