About SUPERFAMILY

SUPERFAMILY is a database of structural and functional annotation for all proteins and genomes.

The SUPERFAMILY annotation is based on a collection of hidden Markov models, which represent structural protein domains at the SCOP superfamily level. A superfamily groups together domains which have an evolutionary relationship. The annotation is produced by scanning protein sequences from over 2,478 completely sequenced genomes against the hidden Markov models.

For each protein you can:

For each genome you can:

For each superfamily you can:

All annotation, models and the database dump are freely available for download to everyone.

SUPERFAMILY is a member of the InterPro consortium of protein annotation databases, and has been integrated into the Ensembl eukaryotic genome project and The Arabidopsis Information Resource. To date, the SUPERFAMILY publications have been cited over 1,000 times. SUPERFAMILY has been used in structural, functional, evolutionary and phylogenetic research projects.
