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.

Dfam_consensus is a related database of Repetitive DNA element sequence alignments and consensus sequence models. This open database provides family consensus models in a format that is compatible with an wide-variety of bioinformatics tools while facilitating the transition to Dfam style profile HMMs.

Dfam project seeks postdoctoral fellow August, 2018
We are excited to announce the opening of a postdoctoral fellowship within the Dfam project and located at the Institute for Systems Biology (ISB) in Seattle. At ISB, the Smit lab is focused on the study of Transposable Element (TE) biology, and evolution using the latest developments in sequence modeling, phylogenetic reconstruction, and homology detection. We have developed […]
