MiRBase Search Mirna

Overview

Search for microRNAs (miRNAs) by name, accession, or keyword using EBI Search over RNAcentral. RNAcentral aggregates miRNA data from miRBase, TarBase, LncBase, and 50+ other databases. Supports filtering by species (e.g., 'Homo sapiens', 'Mus musculus') and RNA type. Returns RNAcentral IDs, descriptions, sequence lengths, and source databases. Use this to find miRNAs like hsa-miR-21-5p, let-7, miR-155, or search by miRBase accession (e.g., MIMAT0000076). Examples: search 'hsa-miR-21' for human miR-21 family, 'let-7 AND TAXONOMY:Homo sapiens' for human let-7 family members.
