Introduction

This peptide family was discovered recently following a BLAST search of various arthropod genomes (Veenstra, 2016). In insects, allatostatin-CCC (AST-CCC) was only found in Locusta migratoria and Athalia rosae genomes. Most insect genomes only contain genes for AST-C and AST-CC but have lost the gene encoding AST-CCC. Just like the other two peptides, AST-CCC contains two cysteine residues that form a disulfidge bridge. However, this peptide also has a C-terminal amide, which is not found in other related peptides.
