The Ensembl project

ThEnsembl project seeks to enable genomic science by providing high quality, integrated annotation on chordate and selected eukaryotic genomes within a consistent and accessible infrastructure.

All data are open access and all software is open source, i.e. freely available to the scientific community. 

The project began in 1999 as a joint project between the EMBL European Bioinformatics Institute and the Wellcome Trust Sanger Institute (then named the Sanger Centre). This changed between 2014 and 2017, with all staff and eventually all hardware moving over to the EMBL-EBI. 

Supported species include comprehensive, evidence-based gene annotations and a selected set of genomes includes additional data focused on variation, comparative, evolutionary, functional and regulatory annotation. The most advanced resources are provided for key species including human, mouse, rat and zebrafish reflecting the popularity and importance of these species in biomedical research.

Frequent updates!

The website and underlying databases (along with the application programming interfaces (APIs)) are updated every 2-3 months. Previous releases of Ensembl can be accessed from the Ensembl Archive.

As of Ensembl release 89 (May 2017), 69 species are supported, along with 16 mouse strains. Associations between sequence variants and diseases, and potential gene regulation sequences across different cell types are among the cutting edge data integrated and displayed in the Ensembl browser and underlying databases.
