The domain content of nematode proteomes.

aany domain that occurred in C. elegans or C. briggsae is ignored.
bproteins are only counted once.
cexcludes proteins from C. elegans and C. briggsae. The domain family may occur in these species, but must also be present in another species to be counted.
dthe taxon specificity is with respect to the nematode taxonomic family. Domains included annotated as “family-specific” here may also be found in other phyla. This is particularly true for PfamA and ProDom domains.
