recommendations! Published in 2022 at "Wiley Interdisciplinary Reviews: RNA"

DOI: 10.1002/wrna.1732

Abstract: Expansion segments (ESs) are multinucleotide insertions present across phyla at specific conserved positions in eukaryotic rRNAs. ESs are generally absent in bacterial rRNAs with some exceptions, while the archaeal rRNAs have microexpansions at regions that… read more here.

DOI: 10.1016/j.molcel.2018.11.023

Abstract: Expansion segments (ESs) are enigmatic insertions within the eukaryotic ribosome, the longest of which resemble tentacle-like extensions that vary in length and sequence across evolution, with a largely unknown function. By selectively engineering rRNA in… read more here.

DOI: 10.1042/bst20231106

Abstract: Ribosomes are universally conserved cellular machines that catalyze protein biosynthesis. The active sites underly immense evolutionary conservation resulting in virtually identical core structures of ribosomes in all domains of life including organellar ribosomes. However, more… read more here.

DOI: 10.1093/gbe/evaa170

Abstract: Abstract The ribosome’s common core, comprised of ribosomal RNA (rRNA) and universal ribosomal proteins, connects all life back to a common ancestor and serves as a window to relationships among organisms. The rRNA of the… read more here.

DOI: 10.1093/gbe/evae173

Abstract: Abstract 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… read more here.

DOI: 10.1261/rna.077123.120

Abstract: The large ribosomal RNAs of eukaryotes frequently contain expansion sequences that add to the size of the rRNAs but do not affect their overall structural layout and are compatible with major ribosomal function as an… read more here.
