Fig. 1. Complete sequence of the Manduca sexta crustacean cardioactive peptide (CCAP) gene. Nucleotide and predicted peptide sequences are listed for the coding region, which starts at nucleotide 1. Blue, CCAP-encoding region; green, dibasic post-translational cleavage sites; red, glycine used for C-terminal amidation; yellow shading, consensus signal peptide sequence; asterisk, stop codon. Intron position and length are indicated above the nucleotide sequence. Intron sequences are shown separately at the bottom, with underlined GT and AG for the intron donor and acceptor consensus sequences, respectively.
