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 41

Rattus norvegicus News

  • RNA updates

    Ensembl RNA data has been updated as follows:

    • New ncRNAs for Zebrafish, Chimp, Medaka, Elephant, Rabbit, Armadillo and Tenrec
    • Updated miRNAs for all chordates.

General News

  • New animated tutorials
    A selection of Ensembl tutorials are now available online as Flash-animated presentations (with popup notes instead of a soundtrack).

  • Compara updates
    Homologies
    Gene trees have been updated to include the 2X genomes and use a multifurcating species tree, and homologues added based on gene trees.

  • Minor schema changes
    analysis_description
    Now has a 'displayable' flag to control whether or not it is usually displayed in the web pages
    xref
    One column has been changed and one added
    • the info_type column has addition ENUM values to give more details about xref provenance
    • A new column 'priority' supports the fetching of xrefs of the same type

    The API has of course been updated to reflect these changes
