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

LkLeucokinin (Lk) encodes a neuropeptide that regulates water balance and food intake. Three groups of leucokinergic neurons are identified in the brain and abdominal ganglion of larvae and adults. Serotonin and insulin peptides have receptors in the abdominal leucokinergic neurons. (160 aa)    
Predicted Functional Partners:
Dh44
Diuretic hormone 44, isoform A; Hormone activity; G protein-coupled receptor binding; diuretic hormone activity; neuropeptide hormone activity. It is involved in the biological process described with: locomotor rhythm; G protein-coupled receptor signaling pathway; neuropeptide signaling pathway; body fluid secretion; hormone-mediated signaling pathway.

CCAP
Crustacean cardioactive peptide (CCAP) encodes a conserved 9 amino acid neuropeptide. It is produced by 1-2 neurons in each segment of the ventral nervous system and is released during the shedding of the old exoskeleton (ecdysis). It also has cardioactive functions.
   
  
 0.852
AstA
Allatostatin-A; May act as a neurotransmitter or neuromodulator.
   
  
 0.840
sNPF
Short neuropeptide F precursor (sNPF) encodes a protein that binds to the product of sNPF-R and activates ERK-Dilps signaling or the PKA-CREB pathway. Its roles include the regulation of cell and organism growth, carbohydrate metabolism, lifespan, feeding behavior, locomotion, circadian rhythm, and sleep.
      
 0.839
Hug
Protein hugin; Probably has a role in larval molting; Belongs to the pyrokinin family.
   
  
 0.837
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 [...]
      
 0.837
Lkr
Leucokinin receptor (Lkr) encodes a 7-transmembrane domain G-protein-coupled receptor (GPCR) with the product of Lk as a ligand. It signals through intracellular calcium, and is implicated in ion regulation by the Malpighian tubules and in feeding control.
      
 0.836
Dh31
Diuretic hormone class 2; Regulation of fluid secretion. Stimulates Malpighian tubules fluid secretion by activating the apical membrane V-ATPase via cyclic AMP of principal cells in the main secretory segment.
   
  
 0.834
Akh
Adipokinetic hormone (Akh) encodes a peptide hormone secreted by the corpora cardiaca. It signals to the G-protein coupled receptor encoded by AkhR to regulate circulating hemolymph carbohydrates and stored lipid and glycogen in the fat body; Belongs to the AKH/HRTH/RPCH family.
   
  
 0.809
Capa
Cardio acceleratory peptide 2b; Capability (Capa) encodes three neuropeptides: two of the periviscerokinin family (CAPA-1 and CAPA-2) and one pyrokinin (pyrokinin-1) that activate the class A GPCRs encoded by CapaR and PK1-R respectively. Capa is expressed in neurosecretory cells innervating corpora cardiaca and abdomen. CAPA-1 and -2 act as diuretic hormones on the Malpighian tubules.
