In bioinformatics, miRBase is a biological database that acts as an archive of microRNA sequences and annotations. As of September 2010 it contained information about 15,172 microRNAs. This number has risen to 38,589 by March 2018. The miRBase registry provides a centralised system for assigning new names to microRNA genes.

Jan 8, 2019 · miRBase catalogs, names and distributes microRNA gene sequences. The latest release of miRBase (v22) contains microRNA sequences from 271 organisms: 38 589 hairpin precursors and 48 860 mature microRNAs.
Nov 13, 2018 · miRBase is the primary public repository and online resource for microRNA sequences and annotation ( http://mirbase.org/ ). Established in 2002 (then called the microRNA Registry), miRBase is responsible for microRNA gene nomenclature and has been assigning gene names for novel microRNA discoveries since that time.
The miRBase database is the primary repository for miRNA sequence annotations. It is the central resource for sequence and structure information of hairpin precursors, known mature miRNA sequences and homologues thereof (Enright and Griffiths-Jones 2008 ).
