5S ribosomal RNA is an integral component of the large subunit of all cytoplasmic and most organellar ribosomes. Its small size and association with ribosomal as well as non-ribosomal proteins made it an ideal model RNA molecule for studies of RNA structure and RNA-protein interactions.

The purpose of this database is to provide information on nucleotide sequences of 5S rRNAs and their genes. The sequences for particular organisms can be retrieved as single files using a taxonomic browser or in multiple sequence structural alignments.
