28S ribosomal RNA is the structural ribosomal RNA (rRNA) for the large subunit (LSU) of eukaryotic cytoplasmic ribosomes, and thus one of the basic components of all eukaryotic cells. It has a size of 25S in plants and 28S in mammals, hence the alias of 25S–28S rRNA. Combined with 5.8S rRNA to the 5' side, it is the eukaryotic nuclear homologue of the prokaryotic 23S and mitochondrial 16S ribosomal RNAs. (en) L'ARN ribosomique 28S est le principal ARN ribosomique constituant la grande sous-unité 60S des ribosomes d'eucaryotes. Chez l'homme, il est constitué de 5 070 nucléotides. Il s'agit d'un ribozyme ayant une activité peptidyl-transférase permettant la formation de liaisons peptidiques entre deux acides aminés durant la protéogenèse. Son équivalent chez les procaryotes est l'ARN ribosomique 23S de la grande sous-unité 50S des ribosomes de procaryotes. Les gènes codant cet ARN sont appelés « ADNr 28S » (28S rDNA en anglais) ; ils peuvent être utilisés pour reconstruire l'arbre phylogénétique de certaines espèces.
