About the Mouse genome

Assembly

Ensembl Mouse is based on the NCBI m37 mouse assembly (April 2007, strain C57BL/6J).

Mouse Genome Sequencing ConsortiumThe Mouse Genome Sequencing Consortium is a joint project between The Whitehead Institute/MIT Center for Genome Research, The Washington University Genome Sequencing Center, The Wellcome Trust Sanger Institute and EMBL - EBI to provide the Mouse genome sequence to the world. We work closely with other Mouse groups to provide an integrated resource (see below for credits).

There are some major changes in the assembly from version m36; for more details see the NCBI build statistics .

For the convenience of our users, we have created a web-based 'wizard' which enables you to convert a GFF file from Mouse assembly m36 to m37.

Annotation

For release 47 the gene annotation presented has been a combined Ensembl-Havana geneset, which incorporates more than 15,000 full-length protein-coding transcripts annotated by the Havana team in addition to the Ensembl automatic gene build. The mouse genome sequence is now considered sufficiently stable that since September 2006 the major genome browsers have come together to produce a common set of identifiers where CDS annotations of transcripts can be agreed and these identifiers are also shown.

Modifications to the systems have further improved the gene set. 95% of the known genes and 47% of the novel genes from build m36 retain the same Ensembl gene ids in this release.

What's New in Ensembl 49

Mus musculus News

  • Mouse transcripts updated
    Several mouse transcripts that were "culled" in Ensembl 47 have been reinstated. Also, a bug in the pipeline that caused ditags to be ignored has been fixed, which has resulted in some shorter UTRs.
  • Minor updates

    A number of minor changes have been made to the core databases.

  • Variation updates
    New variation databases have been released for human, mouse, chicken and zebrafish (dbSNP 128) and rat (dbSNP 126). Transcript variation has been rerun for dog, platypus, chimp, and tetraodon due to gene set changes.
  • Vega updates
    Ensembl Vega has a new Mouse database, and Vega Human no longer shown external Vega annotation.

General News

  • Release schedule

    Ensembl release 50 will occur in July (rather than in April as originally scheduled).
