Alignment of crustacean hyperglycemic hormone (CHH)/molt inhibiting hormone (MIH) precursors. (A) Alignment of prepro-CHH Type I variants. (B) Alignment of CHH Type I and Type II precursors. (C) Alignment of putative MIH prehormones. In this figure, signal peptides are shown in gray, while all mono/dibasic cleavage loci are shown in black. For each sequence, the isoform of CHH/MIH is shown in red, with isoforms of CHH precursor-related peptide shown in pink. Residues (or gaps) that vary between from the top protein in each alignment are highlighted in yellow. In the line below each sequence grouping, amino acids that are identically conserved are indicated by “*”, while conservative amino acid substitutions are marked by “:” or “.”.
