The frameshift database is a comprehensive compilation of experimentally known or computationally predicted data about programmed ribosomal frameshifting. The database provides the graphical view of the frameshift cassettes and the genes utilizing frameshifting for their expression. It also allows the user to find frameshift sites himself/herself from the genome sequences using a program called FSFinder. All the data available in the database can be saved in the extensible markup language (XML) format and downloaded for later analysis. At present, it contains data of frameshift of -1 and +1 type, but more complex type will be added in the future.

4/1/2007 classification of stimulatory secondary structures
- The stimulatory secondary structures of programmed frameshifts are classified into two types: experimental and predicted
3/21/2007 new entry for the white bream virus
- The new entry of PseudoBase relating to programmed frameshift was added to FSDB.
3/12/2007 deletion of a redundant entry
- There were two entries for the turnip yellows virus in different names, so one of them (EM1V0004) were deleted from FSDB.
3/1/2007 changes to the RF2 gene entries
- The wrong annotations of 'shifty' RF2 genes in GenBank were corrected using the results provided by Bekaert et al. (2006), and 25 corrected entries were added to FSDB.
