CC   -!- FUNCTION: Inhibits Y-organs where molting hormone (ecdysteroid) is
CC       secreted. A molting cycle is initiated when MIH secretion diminishes or
CC       stops. Has little or no hyperglycemic activity.
CC   -!- SUBCELLULAR LOCATION: Secreted.
CC   -!- TISSUE SPECIFICITY: Produced by the medulla terminalis X-organ in the
CC       eyestalks and transported to the sinus gland where it is stored and
CC       released.
CC   -!- SIMILARITY: Belongs to the arthropod CHH/MIH/GIH/VIH hormone family.
CC       {ECO:0000305}.
