STRINGSTRING
STRING protein interaction network
Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
a 3D structure is known or predicted
Edges:
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding to each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

SPRSex peptide receptor; Receptor for two functionally unrelated ligands; SP (A70A) for controlling reproductive behaviors and MIP for controlling sleep behavior. MIP-SPR pathway functions as a sleep homeostat which perceives the need for sleep and stabilizes it by providing a slow-acting inhibitory input to the fly arousal system that involve the pigment dispersing factor (pdf) neurons. SP-SPR is one of the multiple SP pathways that induce female post- mating behavioral responses (PMR) such as the suppression of mating receptivity and initiation of egg laying. The PMR switch is achieved [...] (435 aa)    
Predicted Functional Partners:
SP
Accessory gland-specific peptide 70A; Male seminal protein which triggers short- and long-term post-mating behavioral responses (PMR) in female Drosophila. Binds initially to sperm where it is later cleaved to release an active peptide within the female reproductive tract. Signals via the sex peptide receptor (SPR) in female flies; may also act via other receptors. Moderates the activity of distinct neuronal circuitries in the female genital tract to promote specific PMRs including: enhanced ovulation, increased egg laying rate, increased feeding/foraging rate, induced antimicrobial pe [...]

Proc-R
G protein-coupled receptor activity; proctolin receptor activity; neuropeptide receptor activity. It is involved in the biological process described with: G protein-coupled receptor signaling pathway; neuropeptide signaling pathway.
  
  
 0.714
ppk
Amiloride-sensitive Na+ channel; Pickpocket (ppk) encodes an acid-sensing sodium channel from the degenerin/epithelial sodium channel (DEG/ENaC) family. It contributes to mechanical nociception, larval behavior and dendrite morphogenesis.
   
  
 0.676
Dup99B
Ductus ejaculatorius peptide 99B; Induces post-mating responses; increased oviposition and reduced receptivity.
      
 0.668
fru
Sex determination protein fruitless; Probably acts as a transcriptional regulator. Part of the somatic sex determination hierarchy; sex determination genes transformer (tra) and transformer-2 (tra-2) switch fru splicing from the male-specific pattern to the female-specific pattern through activation of the female-specific fru 5'-splice site. Vital for the development of males and females. Controls the development of the male specific abdominal muscle of Lawrence. Plays a role in male courtship behavior and sexual orientation. Enhances male-specific expression of takeout in brain-associ [...]

NPF
Neuropeptide F; Integral part of the sensory system that mediates food signaling, providing the neural basis for the regulation of food response; coordinates larval foraging and social behavior changes during development. Required in dopaminergic (DA) neurons that innervate the mushroom body for satiety to suppress appetitive memory performance; a key factor in the internal state of hunger in the brain. NPF neurons coordinately modulate diverse sensory and motor neurons important for feeding, flight, and locomotion. NPF/NPFR pathway exerts its suppressive effect on larval aversion to d [...]
      
 0.607
Burs
Bursicon (Burs) encodes a cystine knot protein that dimerizes with the product of Pburs to form the bursicon neurohormone. Bursicon neurohormone is released after adult emergence and acts on the receptor encoded by rk for tanning and hardening of the cuticle and expansion of the wings.
      
 0.592
CCHa1-R
Neuropeptide CCHamide-1 receptor; Receptor for the neuropeptide CCHamide-1. Plays a role in the modulation of starvation-induced olfactory behavior where starved flies show increased responsiveness to food odorants, repellants and pheromones.
  
 
 0.589
NPFR
Neuropeptide F receptor; Receptor for NPF. Integral part of the sensory system that mediates food signaling, providing the neural basis for the regulation of food response; coordinates larval foraging and social behavior changes during development. Required in dopaminergic (DA) neurons that innervate the mushroom body for satiety to suppress appetitive memory performance; a key factor in the internal state of hunger in the brain. NPF neurons coordinately modulate diverse sensory and motor neurons important for feeding, flight, and locomotion. NPF/NPFR pathway exerts its suppressive eff [...]

Galphai
G protein alpha i subunit; Guanine nucleotide-binding proteins (G proteins) are involved as modulators or transducers in various transmembrane signaling systems. Plays a role in glial cell differentiation during embryogenesis; loco, Galphao and the G-protein coupled receptor, moody, are required in the surface glia to achieve effective insulation of the nerve cord; Belongs to the G-alpha family. G(i/o/t/z) subfamily.
