About the Zebrafish genome

The zebrafish genome project is a collaboration between the Sanger Institute and the zebrafish community, announced during the Sanger Institute Zebrafish Workshop 2000 and was started in February 2001.

Assembly

This Ensembl website features the zebrafish assembly version 6 (Zv6), as released on 30 March 2006. This assembly was produced by integrating finished clone sequence from the physical map with whole genome shotgun assembly sequence (more information).

The zebrafish sequencing project is funded by the Wellcome Trust.

You may export data from this site. Please see the Conditions of use for these data.

Annotation

This site provides a full Ensembl gene set for Zv6. This release is based on a strategy where transcripts are generated based on protein evidence and clustered in genes. Aligned zebrafish cDNAs are used to add UTR regions. Genes are named based on the alignment of their coding regions to known entries in public databases; ZFIN genes have priority in this process.

What's New in Ensembl 44

Danio rerio News

• Updates to Zebrafish
  Ensembl Danio rerio has been updated with new expression pattern xrefs and DNA align features from ZFIN, and the addition of zebrafish mitochondrial sequence. Biomart also has a new expression pattern database.
• Variation updates
  All species with variation data now have a failed_variation table. Also, in species that have duplicate variations (with the same mapping but different IDs), these have been put into the variation_synonym table.

General News

• ncRNAs for Ensembl chordates
  All Ensembl genebuild databases (i.e. excluding the imported invertebrate databases for mosquitoes, fruit fly, worm and yeast) have been updated with new ncRNA data.
• Compara updates

• Schema changes
  There have been no major schema changes this release, however we are starting to systematically work through the schema to make sure that all column types are appropriate for the data they are likely to hold.
