Only those non-bilaterian sequences that encompass the regions where the amino acid patterns here described are located, and that showed the ANTP-PRD pattern were used. In total 251 non-redundant sequences were used (gi numbers are listed in the appendix). Cases where non-bilaterian genes are clearly misidentified when using amino acid patterns are shown underlined (see text for details). Uncl. – unclassified sequences.

* this signature can also be considered characteristic of NKL genes since only 68% of bilaterian NKL sequences show the ANTP2 pattern
