[Dictionary] Ensembl (Genome Browser)

A genome browser and annotation resource, maintained by EMBL-EBI, that automatically annotates reference genomes -- gene models, transcripts, regulatory features, comparative-genomics alignments -- and integrates that annotation with other biological data (variation, expression, disease association) into one browsable, queryable interface. As of 2022, Ensembl supports 271 registered vertebrate and other model-organism species directly; a sister project, Ensembl Genomes (launched 2009), extends equivalent coverage to invertebrates, plants, fungi, bacteria and protists, together spanning over 50,000 genomes by 2020. Data and software are released under a Creative Commons Attribution 4.0 license, accessible via the website, REST and Perl APIs, BioMart, FTP, and public MySQL databases, with mirror sites at the Sanger Institute (UK) and on AWS (US, Asia).
