miRBase

miRBase is a biological database that serves as the primary repository for microRNA sequences and annotations. Key features:

Contains published miRNA sequences and annotations Assigns stable and consistent names to miRNAs Provides genomic coordinates and secondary structure information Houses high-confidence microRNA annotations Includes predicted miRNA targets Offers sequence search tools Updates regularly with newly discovered miRNAs Covers multiple species

The database is hosted at the University of Manchester and is a critical resource for researchers studying microRNA biology and regulation.
