Rfam
Rfam is a comprehensive database of RNA families, each represented by multiple sequence alignments, consensus secondary structures and covariance models. The database provides curated information for over 4,000 non-coding RNA families and is widely used for RNA annotation, genome analysis, and as training data for machine learning models. Release 15.0 includes expanded coverage with 26,106 genomes, improved 3D structure integration, complete microRNA synchronization with miRBase, enhanced Gene Ontology annotations, and comprehensive viral RNA families.
