?Homoiterons like GGGGGGG stabilize ribosomal RNAs of thermophile prokaryotes.?In eukaryotes, homoiterons are much more abundant in RNA of the larger subunit (LSU).?The LSU repeats increase with phylogenetic rank to 28% entire RNA sequence in hominids.?In mammal LSU RNAs, these repeats constitute 45% of the massive expansion segments.?These repeats may help in anchoring of ribosomes and export of secretory proteins.
