Evolutionary Aspects of Ribosome Biogenesis

Ribosomes are universally conserved large ribonucleoprotein particles ensuring protein synthesis in every cell. The universal conservation of ribosome function and structure offers a unique paradigm for understanding how RNP assembly mechanisms and function have evolved. Consequently, deciphering the general principles and differences of ribosome synthesis and function across the different domains of life can contribute to a better understanding of the evolution history of these fundamental processes. However, to achieve such a level of understanding, it is necessary to define conserved and specific principles of the ribosome life cycle in model organisms representative of all domains of life. Whereas, ribosome synthesis has been well characterized in both bacteria and eukarya, the archaeal ribosome biogenesis pathway is, in contrast, still largely unexplored.

Remarkably, the lack of clear conservation between key ribosome biogenesis factors between bacteria and eukarya suggest that most of the ribosome biogenesis process has been almost reengineered in the course of the evolution. Interestingly, genomic and few in vitro analysis suggest the presence of few known bacterial and eukaryotic ribosomes biogenesis factors in archaeal genomes. Thus, suggesting that the archaeal ribosome biogenesis pathway might proceed via a mixture of bacterial and eukaryotic features to which archaeal specific features have been eventually implemented. Moreover, this also suggests that eukaryotic ribosome biogenesis might have evolved, to some extent, on the basis of a “simplified” archaeal ribosome biogenesis pathway. However, to further shed light on the evolution of this pathway, the fundamental molecular biology of this process still needs to be fully defined in any archaeon.

Therefore, to better characterize the ribosome biosynthesis pathway from an evolutionary perspective and to better understand the conserved molecular principles allowing efficient RNP assembly we are analyzing:

I) Ribosome biogenesis in Archaea

We aim to obtain a comprehensive molecular insights into the “Life” and “Death” of ribosomes in archaea. To this end we are using a multidisciplinary approach to:

1. Define the pre-rRNA processing pathway and its dynamics.
2. Define key cis- and trans-acting elements involved in ribosomal subunits maturation and determine their detailed molecular functions.
3. Define the dynamics of assembly and disassembly of ribosomal precursors.

To achieve these goals we are mostly taking advantage of two genetically tractable model archaeon: the halophilic Euryarchaeota Haloferax volcanii and the thermo-acidophile Crenoarchaeota Sulfolobus acidocaldarius.

II) Comparative structural & functional analysis of the evolutionary conserved RIO protein family in RNP biogenesis

The RIO & RIO-like proteins are evolutionary conserved atypical Kinases/ ATPases involved in the biosynthesis of the small ribosomal subunit and some tRNAs. We aim to better characterize the molecular mechanisms of the RIO protein family. To this end, we are performing comparative structural & functional analysis of the RIO protein family using several archaeal and eukaryotic model organisms.
