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

syd-1Rho GTPase-activating protein syd-1; Probable GTPase activator for the Rho-type GTPases by converting them to an inactive GDP-bound state. Regulates the localization and assembly of presynaptic components during presynaptic development and is required for specifying the identity of axons during initial polarity acquisition. In these roles it is thought to act cell autonomously downstream of syg-1 and syg-2 and upstream of syd-2, possibly as a positive regulator of the latter. Required for the control of movement, egg-laying and the correct localization of elks-1. (987 aa)    
Predicted Functional Partners:
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.

elks-1
Mammalian ELKS/CAST/ERC/Rab6 interacting protein homolog.

nab-1
NeurABin.
   
  
 0.896
rsy-1
Regulator of SYnapse formation.
    
 
 0.852
syg-1
Synaptogenesis protein syg-1; Cell adhesion protein. Involved in synapse formation in the HSNL egg-laying motor neuron. Inhibits assembly of the SCF(sel-10) E3 ubiquitin ligase complex at synapses, and protects them from elimination. Also required for F- actin assembly at the synaptic region and for axon branch formation.
   
 
 0.824
rab-3
Ras-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.
   
  
 0.822
sad-1
Serine/threonine kinase SAD-1; Regulates both neuronal polarity and synaptic organization when bound to strd-1. Kinase activity is required for the establishment, but not the maintenance, of both processes. Binding to nab-1 is essential for role in restricting axonal fate during neuronal polarization but is not required for regulating synapse morphology.

cima-1
MFS domain-containing protein.

nrx-1
NeuReXin related.

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 [...]
