miRBase is the central repository for microRNA (miRNA) sequence information. miRBase has a role in defining the nomenclature for miRNA genes and assigning names to novel miRNAs for publication in peer‐reviewed journals. The online miRBase database is a resource containing all published miRNA sequences, together with textual annotation and links to the primary literature and to other secondary databases. The database provides a variety of methods to query the data, by specific searches of sequences and associated text and literature. All miRBase data are also available for download from the miRBase FTP site. Curr. Protoc. Bioinform. 29:12.9.1‐12.9.10. © 2010 by John Wiley & Sons, Inc.
