Dfam 2.0 (September 2015, 4150 entries)
The Dfam database is a collection of Repetitive DNA element sequence alignments, hidden Markov models (HMMs) and matches lists for complete Eukaryote genomes. More...
Transposable elements (or interspersed repeats) account for a substantial portion of eukaryotic genomes. Accurate annotation of TEs enables research into their biology and can shed light on the evolutionary processes that shape genomes. Dfam represents a collection of alignments and HMMs of such transposable elements and other repetitive DNA elements. The Dfam website gives information about each model, and provides genome annotations for a collection of core genomes. The models may also be downloaded from the ftp site, for example to mask repeats in new genomes.

Meet Dfam2.0 October, 2015
Dfam is growing up. This is the first major expansion of the database since it’s inception. We’ve added repeat families from four new organisms: mouse, zebrafish, fruit fly, and nematode. In total, this release includes 2,844 new familes ( 4,150 total ). New organisms and coverage In expanding Dfam to include families from multiple genomes, […]
