We aim at deepening our molecular understanding of non-protein-coding RNAs (ncRNAs) in large ribonucleoprotein (RNP) complexes. In particular we study the ribosome and the vault complex. To unravel the functional contributions of specific rRNA nucleotides for protein synthesis, we have developed an ‘atomic mutagenesis’ approach. This tool allows manipulating single functional groups or even single atoms of rRNA residues within the ribosome. To study translation regulation, we recently performed genomic screens seeking for novel small ncRNAs that directly bind and possibly regulate translating ribosomes in model organisms from all three domains of life.
