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

rab-3Ras-related protein Rab-3; Involved in exocytosis by regulating a late step in synaptic vesicle fusion. Could play a role in neurotransmitter release by regulating membrane flow in the nerve terminal (By similarity). Plays a role in the recruitment of endophilin unc-57 to synaptic vesicles. Probably by controlling dense-core vesicle trafficking, plays a role in the AVG neuron-mediated formation of the right axon tract of the ventral nerve cord. Belongs to the small GTPase superfamily. Rab family. (233 aa)    
Predicted Functional Partners:
unc-10
Rab-3-interacting molecule unc-10; Regulates the efficiency of a post-docking step of the release pathway. Acts after vesicle docking likely via regulating priming. May regulate the conformational changes in syntaxin. Binding of vesicles via rab-3[GTP] to Rim may signal the presence of a docked synaptic vesicle. Rim may then signal to unc-13 to change the conformation of syntaxin from the closed to the open state. Syntaxin could then engage synaptobrevin on the docked vesicle to form SNARE complexes and to prime the vesicle for release. Not required for the development or the structura [...]

syd-2
Liprin-alpha; May play a role in regulating the structure of the neuronal region, called the active zone, from which synaptic vesicles send neurotransmitter signals across the synapse. This may be in association with the liprin-beta protein hlb-1 ; Belongs to the liprin family. Liprin-alpha subfamily.
   
 
 0.983
snt-1
Synaptotagmin-1; May have a regulatory role in the membrane interactions during trafficking of synaptic vesicles at the active zone of the synapse. It binds acidic phospholipids with a specificity that requires the presence of both an acidic head group and a diacyl backbone (By similarity). Involved in necrotic cell death.
   
 0.975
unc-17
Vesicular acetylcholine transporter unc-17; Involved in acetylcholine transport into synaptic vesicles. Belongs to the major facilitator superfamily. Vesicular transporter family.
   
 
 0.946
rimb-1
RIM Binding protein.
   
 
 0.945
snb-1
Synaptobrevin-1; Involved in the targeting and/or fusion of transport vesicles to their target membrane. Acts in neuronal exocytosis of synaptic transmission. Likely to have a role in cholinergic transmisson. Required for viability, coordinated movement and M3 pharynx motor neuron function.
   
 
 0.942
rbf-1
Rabphilin-1; Rab-3 effector.
   
 
 0.939
snn-1
ATP-grasp domain-containing protein.
   
 0.939
snt-4
SyNapTotagmin.
   
 
 0.934
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.
