About Rat Ensembl
Rat Genome Project 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.

Ensembl is working with the broader rat genomics community (RGD) to provide annotation of the rat genome.

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