About the Rat genome

Assembly

RatThe latest build provides a preliminary data set based on the version 3.4 "November 2004 Update" of the rat genome assembly. In this update a 15 bp overhang was removed at the join between AABR03100354-AC117058 and the order was reversed for BACs AC133000 and AC136926.

The Rat Genome project is an international collaboration to sequence the genome of the brown rat (Rattus norvegicus). The DNA sequence is generated by Baylor College of Medicine, Celera Genomics, Genome Therapeutics, The Institute for Genome Research, and The University of British Columbia.

The rat data used on this site can be downloaded directly from Baylor College of Medicine.

Annotation

Ensembl is working with the broader rat genomics community (RGD) to provide annotation of the rat genome. The latest release (August 2006) uses a new rat-specific repeat library, and takes advantage of additional cDNAs and ESTs which have been published since the original RGSC 3.4 genebuild, with the result that around 1800 new gene predictions have been added.

What's New in Ensembl 44

Rattus norvegicus News

  • 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.
