miRNA history

Keep track of the annotation of your miRNA of interest throughout time. Enter a precursor/mature miRNA name, sequence or accession number and get an overview of how the nomenclature, sequence and other annotation changed in the different releases of the miRBase database.

miRNA update

Get the most up to date annotation for your miRNA(s) of interest. Enter a precursor/mature miRNA name, sequence or accession number and find out whether it is still annotated in the most recent release of the miRBase database and/or how the annotation changed. Alternatively, upload a file containing information for multiple miRNAs.

miRBase release comparison

Compare different releases of the miRBase database. Specify two releases and find out which miRNA records were added, removed or changed in annotation.
