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

Predicted Functional Partners:
lgg-1
Protein lgg-1; Ubiquitin-like modifier involved in the formation of autophagosomal vacuoles (autophagosomes). When lipidated mediates tethering between adjacent membranes and stimulates membrane fusion during autophagy. Recruits lipidated-lgg-2 to maturing autophagosomes. Acts in the aggrephagy pathway, which is the macroautophagic degradation of ubiquitinated protein aggregates, and preferentially interacts with autophagy proteins and substrates containing LIR motifs to mediate autophagosome formation and protein aggregate degradation. In particular, binds to components of the unc-51- [...]

epg-7
ATG11 domain-containing protein.
   
 
 0.970
lgg-2
Protein lgg-2; Ubiquitin-like modifier involved in the formation of autophagosomal vacuoles (autophagosomes). When lipidated mediates tethering between adjacent membranes and stimulates membrane fusion. Less effective at promoting membrane fusion than lgg-1. Acts upstream of the autophagy protein epg-5 in the aggrephagy pathway, which is the macroautophagic degradation of ubiquitinated protein aggregates, and preferentially interacts with autophagy proteins and substrates containing LIR motifs to mediate autophagosome formation and protein aggregate degradation. In particular binds to [...]
   
 
 0.907
atg-18
Autophagy-related protein 18; Component of the autophagy machinery that is recruited to phosphatidylinositols on preautophagosomal structures, which are early autophagic structures, to promote autophagosome formation, and the subsequent degradation and clearance of engulfed apoptotic cells and P- granules in somatic cells. In particular, binds with high affinity to phosphatidylinositols including phosphatidylinositol 3-phosphate (PtdIns(3)P), phosphatidylinositol 4-phosphate (PtdIns(4)P), and phosphatidylinositol 5-phosphate (PtdIns(5)P), and more weakly to phosphatidylinositol 3,5-bis [...]
   
 
 0.851
sepa-1
Protein sepa-1; Adapter protein that connects P-granules in somatic cells with the autophagic machinery. Association with other adapters such as epg-2 and P-granule components such as pgl-3 is required for the accumulation and degradation of P-granules by autophagy in somatic cells. This ensures exclusive localization of the P-granules in germ cells.
      
 0.850
bec-1
Beclin homolog; Regulates autophagy. Together with phosphatidyl-3-phosphate kinase vps-34, acts as a core subunit of the PI3K complex that mediates formation of phosphatidylinositol 3- phosphate (PtdIns3P), thereby regulating membrane trafficking. In association with sorf-1 and sorf-2, negatively regulates phosphatidylinositol 3- phosphate in early endosomes to allow for the conversion to late endosomes. Involved in the clearance of engulfed apoptotic cell corpses. Together with ced-9, negatively regulates somatic and germline apoptosis. Plays a role in endosome-to-Golgi retrograde tra [...]
   
 
 0.822
rpl-43
60S ribosomal protein L37a; Belongs to the eukaryotic ribosomal protein eL43 family.
   
  
 0.810
hlh-30
BHLH domain-containing protein.
   
 
 0.801
epg-2
Ectopic P granules protein 2; Involved in autophagy. Thought to act as an adapter protein that brings PGL granules to autophagic structures containing lgg-1. Association with other adapters such as sepa-1 is required for the accumulation and degradation of germ cell specific P-granules by autophagy in somatic cells. This ensures exclusive localization of the P-granules in germ cells. May also play a role in the removal of sepa-1 from somatic cells.
   
 
 0.778
atg-7
Ubiquitin-like modifier-activating enzyme ATG7; E1-like activating enzyme involved in the 2 ubiquitin-like systems required for autophagy.
