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.

In order to interpret the molecular basis of the translational process, it is essential to have a corresponding knowledge of the higher structure of the ribosome. A large amount of biochemical data about structure of the ribosome is available at present. Ribosomal cross-linking is one of the most important methods which allows us to get such data.

The IRESite database contains information about the experimentally studied IRES (Internal Ribosome Entry Site) segments. IRES regions are known to attract eukaryotic ribosomal translation initiation complex and thus promote translation initiation independently of the presence of the commonly utilized 5'-terminal 7mG cap structure.

This database compiles all complete or nearly complete SSU (small subunit) and LSU (large subunit) ribosomal RNA sequences. Sequences are provided in aligned format. The alignment takes into account the secondary structure information derived by comparative sequence analysis of thousands of sequences. Additional information such as literature references, taxonomy, secondary structure modles and nucleotide variability maps, is also available.
