The gene short neuropeptide F precursor is referred to in FlyBase by the symbol Dmel\sNPF (CG13968, FBgn0032840). It is a protein_coding_gene from Drosophila melanogaster. Based on sequence similarity, it is predicted to have molecular function: neuropeptide hormone activity. There is experimental evidence that it is involved in the biological process: larval feeding behavior; regulation of trehalose metabolic process; determination of adult lifespan; positive regulation of cell size; positive regulation of insulin receptor signaling pathway; regulation of glucose metabolic process; positive regulation of ERK1 and ERK2 cascade; multicellular organism growth; adult feeding behavior; positive regulation of multicellular organism growth. 13 alleles are reported. The phenotype of these alleles is annotated with: embryonic/larval fat body. It has one annotated transcript and one annotated polypeptide. Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of moderate expression to a trough of no expression detected. Peak expression observed within 18-24 hour embryonic stages, during early larval stages, at stages throughout the pupal period, in adult male stages. Summary of FlyAtlas Anatomical Expression Data: Expression at high levels in the following post-embryonic organs or tissues: adult brain. Expression at moderate levels in the following post-embryonic organs or tissues: adult head, larval/adult central nervous system. Comments on Affy2 ProbeSet: ProbeSet 1624838_a_at completely aligns to an exonic region common to each of the 2 FlyBase-annotated transcript isoforms of sNPF. Gene sequence location is 2L:20027915..20056373.

In situ labelling closely approximates that of antisera labelling in both adults and larvae. At the larval stage approximately 35 neurons per hemisphere, other than the Kenyon cells, are positive for sNPF mRNA. These cells are located dorsally and ventrally and include three strongly labelled neurons with large cell bodies that are probably neurosecretory cells. In each of the thoracic and abdominal neuromeres of the larval ventral nerve cord, three to four lateral cell bodies and one dorso-medial cell body express sNPF transcript. In abdominal neuromeres A7 and A8 there are additional labelled cell bodies with large diameters, and a pair of large dorso-medially located cell bodies expressing sNPF transcript are found in abdominal segment A1. In adults, expression of sNPF transcript is seen in approximately 280 neuronal cell bodies other than the Kenyon cells. The approximately 28 neurons distributed in the adult subesophageal ganglion are located in three bilateral clusters: one cluster close to the esophageal foramen; another ventrolateral in the ganglion; and a third cluster dorsolateral in the ganglion. At the base of the adult optic lobe there are clusters of about 50 small cell bodies distributed anteriorly and posteriorly. Several clusters of sNPF-XR expressing cells are located in the adult dorsal protocerebrum, mostly in the posterior with only approximately four cells located anteriorly.
Late embryonic expression of sPNF transcript is observed in the antennomaxillary sense organ, in the posterior of the brain hemispheres, in the fused ventral ganglion, and in bilaterally symmetrical pairs of cells along the ventral midline of the ventral ganglion. In the third instar larval central nervous system, expression is observed in the dorsal anterior region of the protocerebrum of the brain hemispheres, in cells of the subesophageal ganglion, along the ventral midline, and in the thoracic and abdominal segments of the ventral ganglion.
In the adult sNPF protein is expressed in three neurons of the LNd cluster. Two of these LNd neurons also express Scer\GAL4Mai179 and do not correspond to the LNd neurons labeled by Scer\GAL4npf.4.5 in males. In late third instar larva, sNPF protein is expressed in two s-LNv Pdf neurons. These two s-LNv Pdf neurons are also labeled by Scer\GAL4NP6301.
sNPF peptide is found in neurons in the dorsal anterior of the larval prototcerebrum, and in six projecting axons of the thoracic ventral ganglion, and in axons of the descending connectives in the abdominal ventral ganglion. In the adult, sNPF peptide is found in the medulla of the optic lobe and in the calyx of the mushroom body.
Antisera labelling closely approximates that of in situ labelling in both adults and larvae. sNPF protein appears to be expressed in most of the approximately 600 larval Kenyon cells, and in 190-200 cells of the larval central nervous system, approximately 70 of which are in the brain (including the subesophageal ganglion) and a minimum of 120 in the thoracic and abdominal neuromeres. Three pairs of intensely immunolabelled cells (referred to as LNCs) located dorsally in the protocerebrum are probably neurosecretory cells of the pars lateralis and have axons terminating in the ring gland and anterior aorta. Processes of sNPF immunopositive larval cells are seen in neuropils of the protocerebrum, deutocerebrum, subesophageal ganglion, and most densely in the lobes of the mushroom body. Further processes are seen in the larval optic center, non-glomerular neuropils surrounding the mushroom body lobes, and the pars intercerebralis and lateralis. In the abdominal and thoracic neuromeres of the larval ventral nerve cord, sNPF immunopositive cells are located dorsally, ventrally and laterally. In larval abdominal neuromeres A7 and A8 there are additional immunopositive cell bodies with large diameters, and a pair of large dorso-medially located cell bodies expressing sNPF-XP are found in abdominal segment A1. Two bundles of sNPF immunopositive fibres are found in the ventral ganglia associated with the dors-median and ventro-median tracts. Expression was also seen in two layers of the fan shaped body of the central complex, and in the basal portion of the medulla. Expression within the antennal lobe is located within the olfactory receptor neurons, as determined by coexpression of Scer\GAL4Cha.7.4.
Summary of FlyAtlas Anatomical Expression Data: Expression at high levels in the following post-embryonic organs or tissues: adult brain. Expression at moderate levels in the following post-embryonic organs or tissues: adult head, larval/adult central nervous system.
