MirGeneDB

Introduction

MirGeneDB is a database of manually curated microRNA genes that have been validated and annotated, as initially described in Fromm et al. 2015. Maintained by ELIXIR Norway, MirGeneDB 2.1 includes more than 16,000 microRNA gene entries representing over 1,500 miRNA families from 75 metazoan species.

Key Features

  • Curated and validated — all entries are manually curated with consistent annotation standards
  • Broad taxonomic coverage — 75 metazoan species across more than 1,500 miRNA families
  • Browse, search, and download — full access to all microRNA gene data
  • Expression heatmaps — normalized expression visualization (RPM) for each species with downloadable count matrices
  • Overview page — summary representation of all data with simple navigation through gene- and species-rich sections
  • Applications — supports research in gene regulation, evolutionary biology, and disease mechanisms

Getting Started

  1. Visit the MirGeneDB website to browse miRNA genes by species or family
  2. Use the search function to find specific microRNA genes
  3. Download count matrices and expression data for your analyses
