miROrtho: the catalogue of animal microRNA genes




This form allows to query for:
  • A known miRNA family (e.g. "mir-204")
  • A list of known miRNA families (e.g. "mir-204, mir-205")
  • All miRNA genes in one genome (e.g. "Dere")
  • New miRNA groups (e.g. "22015")
  • "%" is the wildcard character

miROrtho contains predictions of precursor miRNA genes covering several animal genomes combining orthology and a Support Vector Machine. We provide homology extended alignments of already known miRBase families and putative miRNA families exclusively predicted by our SVM and orthology pipeline.
