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-21Carboxypeptidase 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. (472 aa)    
Predicted Functional Partners:
egl-3
Neuroendocrine 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. [...]

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 [...]

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.
   
  
 0.773
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.

kpc-1
Furin-like protease kpc-1; Furin-like protease which cleaves proproteins at the RX(K/R)R consensus motif. During neuronal development, regulates the formation and extension of dendrite branches and cellular positioning of various type of neurons. Promotes the formation, extension and self-avoidance of dendritic branches of PVD and FLP mechanosensory neurons. In PVD neurons, regulates plasma membrane levels of branching receptor dma-1 by targeting it to late endosomes and thus promotes normal dendrite branching and dendrite self-avoidance. Also controls dendrite extension in AIY and D-t [...]

pkc-1
Protein kinase C-like 1B; PKC is activated by diacylglycerol which in turn phosphorylates a range of cellular proteins. PKC also serves as the receptor for phorbol esters, a class of tumor promoters. Involved in neuropeptide secretion in motor axons. Likely to act via the extracellular signal-regulated kinase/mitogen-activated protein kinase (ERK/MAPK) pathway in the signaling response to various sensory neurons; temperature, odor, taste, and osmolality. Its role in regulation differs depending on the neuron in which it is acting; thermosensation in AFD neurons, osmolality in ASH neuro [...]
