General Information

  • ID:  hor003125
  • Uniprot ID:  Q9VET0
  • Protein name:  Neuropeptide F
  • Gene name:  NPF
  • Organism:  Drosophila melanogaster (Fruit fly)
  • Family:  NPY family
  • Source:  Animal
  • Expression:  Expression is high in larvae seeking food and is down-regulated in late embryos coinciding with the onset of the behavior of older larvae, including food aversion, hypermobility, and cooperative burrowing. In males, expression is increased by mating and r
