ProteomicsReduction of ribosomal expansion segments in yeast species of the Magnusiomyces/Saprochaete clade
Ribosomes are ribonucleoprotein complexes highly conserved across all domains of life. The size differences of ribosomal RNAs (rRNAs) can be mainly attributed to variable regions termed expansion segments (ESs) protruding out from the ribosomal surface. Although the ESs were found to be involved in ...

ProteomicsGene- and species-specific Hox mRNA translation by ribosome expansion segments
Ribosomes have been suggested to directly control gene regulation, however regulatory roles for ribosomal RNA (rRNA) remain largely unexplored. Expansion segments (ESs) consist of multitudes of tentacle-like rRNA structures extending from the core ribosome in eukaryotes. ESs are remarkably variable ...

ProteomicstRNA synthetases are recruited to yeast ribosomes by rRNA expansion segment 7L but do not require association for func-tionality
Ribosomes expanded during evolution on the protein and rRNA level. The expanded regions do not change the active sites of ribosomes and thus do not alter the peptide bond formation reaction catalysed by the ribosome. To what purpose these expansions were selected is not fully understood. Here, we de...
