Adipokinetic hormone II (Locusta migratoria)  (Synonyms: Lom-AKH-II)

Adipokinetic hormone II (Locusta migratoria) (Lom-AKH-II) is a insect adipokinetic hormone (AKH), enhances fat body cAMP levels in vitro. Insect adipokinetic hormones (AKHs) controls flight-directed mobilization of carbohydrate and lipid from fat body stores, which depends on AKH receptor(s) coupling to cAMP formation and glycogen phosphorylase activation via the stimulatory guanine nucleotide-binding protein (Gs)^[1][3].

Adipokinetic hormone II (Locusta migratoria) (radiolabeled; 1 pmol in 10 μL of 10% methanol; 30 min on ice, and repeated for 2 h at 30 °C) shows no association with one of the larger protein components, indicating a lack of separate transporting or carrier protein in the hemolymph^[1].
Adipokinetic hormones (AKHs) are known to be involved in insect immunity and shows the mechanism of metabolic stimulation, leading a significant increase in carbon dioxide production, and efficacy increase of toxins produced by I. fumosorosea in the cockroach's body^[2].
Adipokinetic hormone II is more effective than hormone I in bringing about an accumulation of cAMP in the fat body^[4].

Adipokinetic hormone II (Locusta migratoria) (1 pmol in 10 μL of 10% methanol; injection) plays its own biol. role in the overall syndrome of insect flight, with different half-lives of 40 min and 37 min during rest and flight, respectively^[1].
