Function
Ligand for the sex peptide receptor (SPR) (PubMed:20308537, PubMed:20458515, PubMed:25333796). Stabilizes sleep and maintains sleep homeostasis to inhibit the activity of wake-promoting circuits, such as those that involve the pigment dispersing factor (pdf) neurons. Regulated by the circadian clock network and pathways associated with a sleep homeostat (PubMed:25333796). May also have a regulatory role in gut motility (PubMed:11181081).
