Sample entry of UTRdb. Specialized information not present in the primary EMBL/GenBank database is shown in bold case with active crosslinks with other databases underlined. The ‘UT’ line reports information about completeness or not of the relevant UTR entry (e.g. complete or partial) as well as the number of spanned exons in the case of genomic DNA sequences. The presence in this sequence entry of a ‘5′ribosomal mRNA TOP’ (32–34) (UTRsite entry: U0010) and of a microsatellite element has also been annotated.
