Fig. 1From: Pharmacological and functional similarities of the human neuropeptide Y system in C. elegans challenges phylogenetic views on the FLP/NPR systemC. elegans and human peptide alignment. Amino acid sequences of C. elegans and human peptides aligned to the amidated C terminus (a-amide, conserved C-terminal RF/Ya and additional R at − 4 position highlighted in black rectangles). C. elegans peptide syntax consists of gene and isoform. Amino acids are colored according to their properties (Lesk scheme [26])Back to article page
