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

egl-3Neuroendocrine convertase 2; Serine endoprotease which cleaves preproteins at paired basic amino acids. Processes FMRFamide-like (flp) and neuropeptide-like protein (nlp) neuropeptides. Probably by processing flp-1 and flp-18, modulates the neuronal excitation-inhibition balance and thus the level of activity of the locomotor circuit. Regulates sensitivity to mechanosensory stimuli. By processing neuropeptides, modulates basal acetylcholine release at the ventral cord neuromuscular junctions. Probably by processing flp neuropeptides, regulates the turning step of male mating behavior. [...] (652 aa)    
Predicted Functional Partners:
egl-21
Carboxypeptidase E; During FMRFamide-like peptide (FaRPs or FLP) and neuropeptide-like protein (NLP) precursor processing, catalyzes the removal of Arg or Lys residues from the C-terminus following the initial endoprotease cleavage. By processing neuropeptides, modulates basal acetylcholine release at the ventral cord neuromuscular junctions. Involved in egg-laying, defecation and locomotion. By processing FLP neuropeptides, regulates the turning step of male mating behavior. Involved in reducing pharyngeal pumping in response to high CO(2) levels.

sbt-1
Seven B Two (Mammalian 7BT prohormone convertase chaperone) homolog.

ida-1
Receptor-type tyrosine-protein phosphatase-like ida-1; Regulates dense-core vesicle (DCV) trafficking and/or secretion. Probably by controlling DCV trafficking, plays a role in the AVG neuron-mediated formation of the right axon tract of the ventral nerve cord. Involved in locomotion by regulating acetylcholine release. Probably by controlling the secretion of FLP neuropeptides, regulates the turning step of male mating behavior. Plays a role in preventing dauer formation. Belongs to the protein-tyrosine phosphatase family. Receptor class 8 subfamily.

unc-31
Calcium-dependent secretion activator; Calcium-binding protein involved in exocytosis of vesicles filled with neurotransmitters and neuropeptides. Probably acts upstream of fusion in the biogenesis or maintenance of mature secretory vesicles. May specifically mediate the Ca(2+)-dependent exocytosis of large dense-core vesicles (DCVs) and other dense-core vesicles (By similarity). Specifically required to activate the neuronal G-alpha pathway. Functions with G-alpha proteins from the same motor neurons to regulate locomotion. Involved in regulating entry into quiescence triggered by sat [...]

flp-3
FMRFamide-like neuropeptides 3; FMRFamides and FMRFamide-like peptides are neuropeptides. SAEPFGTMRF-amide inhibits the activity of dissected pharyngeal myogenic muscle system; Belongs to the FARP (FMRFamide related peptide) family.
   
  
 0.764
nlp-21
Neuropeptide-Like Protein.
   
  
 0.739
unc-13
Phorbol ester/diacylglycerol-binding protein unc-13; May form part of a signal transduction pathway, transducing the signal from diacylglycerol to effector functions. One such function could be the release of neurotransmitter from neurons. Probably by regulating neuronal transmission downstream of lin-3 and receptor lin-23 and phospholipase plc-3 and upstream of innexin unc-7 and egl-4/PKG in ALA neurons, involved in the decrease in pharyngeal pumping during the quiescent state that precedes each larval molt.
   
  
 0.726
flp-1
FMRFamide-like neuropeptides 1; Together with flp-18, plays a homeostatic role by acting on the GABAergic neural transmission at neuromuscular junctions to prevent overexcitation of the locomotor circuit. DPNFLRF-amide: Inhibits the activity of dissected pharyngeal myogenic muscle system; Belongs to the FARP (FMRFamide related peptide) family.
   
  
 0.719
eat-4
Probable vesicular glutamate transporter eat-4; Required for glutamatergic synaptic transmission. In AWB and AWC sensory neurons, required for the detection of preferred food sources, probably via glutamatergic neurotransmission from sensory neurons. Negatively regulates the turning step of male mating behavior.
   
  
 0.713
tdc-1
Tyrosine decarboxylase; Required for the decarboxylation of tyrosine to tyramine, a precursor of octopamine but probably also itself a neurotransmitter. Involved in the regulation of egg laying, which is inhibited by tyramine. Also involved in controlling locomotion and head movements. Due to its involvement in octopamine biosynthesis, also required for crtc-1-dependent regulation of AMPK-mediated longevity which requires octopamine signaling ; Belongs to the group II decarboxylase family.
