Atlas of UTR Regulatory Activity

The Atlas of UTR Regulatory Activity (AURA), a biological database, now in its second version, is a manually curated and comprehensive catalog of human 5' and 3' untranslated sequences (UTR) and UTR regulatory annotations. It includes basic annotation, phylogenetic conservation, binding sites for RNA-binding proteins and miRNA, cis-elements, RNA methylation and editing data, and more, for human and mouse.
