The Evolution of FMRFamide-Like Neuropeptide Genes
Biologically active peptides constitute an important class of extracellular molecular messengers. Consisting of short chains of amino acids, they mediate a range of behavioral, developmental, and physiological processes and are major components of both neuronal and endocrine communication networks (Krieger, 1983). In general, peptides are initially contained on larger precursor proteins which undergo post-translational proteolytic processing (Loh and Gainer, 1983). These precursors often serve as polyproteins to liberate multiple bioactive peptide products, a property that greatly increases their potential information capacity.
