All pairs of domain combinations at the superfamily level are listed here.
The identification of domain pairs does not account for the possibility of non-contiguous domains. Inserted, or interlaced, domains are seen as having a simple pair ordering.
The links below permit the addition or removal of specific sets of domain combination pairs.
Change the list of genome two-letter codes in the 'Include genomes' box to include domain-pairs from those genomes.
Change the list of genomes in the 'Exclude genomes' box to exclude domain-pairs from those genomes.
