Table 2 Sequence identities between P. acuta ECE-like proteins and ECE homologs in other organisms. The three P. acuta ECE-like proteins are L-form (TRINITY_DN14970_c0_g1_i2), N-form (TRINITY_DN4184_c0_g1_i8), and C-form (TRINITY_DN36866_c0_g1_i3). Reference sequences were downloaded from the NCBI protein database (human: BAA07800; mouse: NP_001356106; zebrafish: NP_001071260; hydra: AAD46624)
