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

nlp-40Neuropeptide-like peptides nlp-40; [Peptide P3]: Neuropeptide ligand for the G-protein coupled receptor aex-2. Activates and regulates the rhythmic calcium influx in DVB GABergic neurons during the defecation motor program, which is a coordinated series of three muscle contractions that occurs every 45 seconds. (123 aa)    
Predicted Functional Partners:
aex-2
G-protein coupled receptor aex-2; G-protein coupled receptor for the nlp-40 neuropeptide. The activity of this receptor is mediated by G proteins which activate adenylyl cyclase. Plays a role in the defecation motor program, which is a coordinated series of three muscle contractions that occurs every 45 seconds. Specifically, acts in GABAergic neurons, such as AVL and DVB, to control the expulsion step of defecation. Required for fatty acid uptake and metabolism by intestinal cells and therefore regulates the levels of triglycerides in the intestine.

aex-1
C2 domain-containing protein aex-1; Involved in retrograde signaling from post-synaptic cells to pre-synaptic neurons, probably by regulating vesicle exocytosis in post-synaptic cells. Acts in muscles, to regulate the localization of synaptic vesicle fusion protein unc-13 likely during vesicle exocytosis and thus regulate retrograde signaling at the neuromuscular junction (NMJ). Regulates anterior body muscle contractions (aBOC) and the expulsion steps during the defecation motor program (DMP). Probably by regulating DMP, plays a homeostatic role in the uptake of triglycerides. Regulat [...]

K02A11.4
Saposin B-type domain-containing protein.
   
  
 0.708
aex-4
t-SNARE protein aex-4; t-SNARE protein which regulates the secretion of aex-5 from intestinal cells. Involved in the defecation motor program, which is a coordinated series of three muscle contractions that occurs every 45 seconds; Belongs to the SNAP-25 family.
   
  
 0.672
pbo-4
Na(+)/H(+) exchanger protein 7; Na+/H+ exchanger which mediates the transient acidification of the coelomic space and plays a role in contraction of posterior body muscles during defecation. Probably by regulating the defecation motor program, required for fatty acid uptake by intestinal cells.

nlp-8
Neuropeptide-Like Protein.

aex-5
Endoprotease aex-5; Probable serine endoprotease which cleaves preproteins at paired basic amino acids. May process FMRFamide-like (flp) and neuropeptide-like protein (nlp) neuropeptides. In muscles, involved in neuronal retrograde signaling by regulating presynaptic activity and localization of synaptic vesicle fusion protein unc-13 at the neuromuscular junction (NMJ). Acts in the intestine to regulate anterior body muscle contractions (aBOC) and the expulsion steps during the defecation motor program (DMP). Probably by regulating DMP, required for fatty acid uptake by intestinal cell [...]

pbo-6
Proton-gated ion channel subunit pbo-6; Forms a proton-gated ion channel with pbo-5 that is activated by acidification of the posterior coelomic space, leading to posterior body wall muscle contraction (pBoc) during the defecation cycle. Not necessary for stimulation of posterior body contraction (pBoc). Does not bind neurotransmitters such as acetylcholine, gamma-aminobutyric acid, glycine, serotonin, glutamate or choline.
