Fig. 3From: Identification of the neuropeptide precursor genes potentially involved in the larval settlement in the Echiuran worm Urechis unicinctusFRWamide, FILamide and FxFamide neuropeptide precursors. a, b and c Schematics of FRWamide, FILamide and FxFamide precursor proteins in U. unicinctus. N-terminal signal peptides (green) and the predicted peptides (gray) flanked by basic cleavage sites (red) are shown. The predicted mature FRWamide, FILamide and FxFamide sequences and their numbering as used in the text are listed. d, e and f Multiple alignments and peptide logos of the predicted mature FRWamide (GenBank: MT162138), FILamide (GenBank: MT162136) and FxFamide (GenBank: MT162135)Back to article page
