Is exclusively composed of 4 tightly packed alpha helices (no beta strand is present). LD(50) is 198 +- 33 pmol/g when injected into the ventro-lateral thoracic region of adult blowflies (L.cuprina) (at 24 hours post-injection) (PubMed:26073605). PD(50) is 0.89 nmol/g when injected into tobacco budworm (PubMed:9589602). PD(50) is 0.78 nmol/g when injected into cabbage looper (PubMed:9589602). PD(50) is 0.9 nmol/g when injected into beet army worm (PubMed:9589602). PD(50) is 2.0 nmol/g when injected into Southern corn rootworm (PubMed:9589602). Arose via modification of ancestral neuropeptide hormones (ion transport peptide/crustacean hyperglycemic hormones (ITP/CHH)). Belongs to the helical arthropod-neuropeptide-derived (HAND) family.
