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

epg-3Ectopic P granules protein 3; Involved in autophagy. Thought to act in autophagasome and omegasome formation. (458 aa)    
Predicted Functional Partners:
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 [...]

atg-13
Autophagy-related protein 13 homolog; Component of the unc-51/atg-13 complex required for autophagosome formation. Required for the degradation of germ cell specific P-granule components such as sepa-1 by autophagy in somatic cells. This ensures exclusive localization of the P-granules in germ cells. May function downstream of the let-363 (Tor) signaling pathway to mediate sepa-1 degradation. Plays a role in survival during limited food availability ; Belongs to the ATG13 family. Metazoan subfamily.

epg-4
Ectopic P granules protein 4; Involved in autophagy. Thought to act in autophagasome and omegasome formation.
      
 0.925
epg-5
Ectopic P granules protein 5; Involved in the maturation of autophagosomes into autolysosomes during starvation-induced autotrophy. Specifically, involved in the clearance of apoptotic cells by promoting the delivery of engulfed apoptotic cells to the lysosome.

lgg-3
Ubiquitin-like protein atg-12; Ubiquitin-like protein involved in autophagy vesicles formation (By similarity). Conjugation with atg-5 through a ubiquitin- like conjugating system involving also atg-7 as an E1-like activating enzyme and atg-10 as an E2-like conjugating enzyme, is essential for its function (By similarity). Most likely a component of an atg-5-lgg- 3-atg-16 complex that promotes autophagosome formation by associating with lgg-2, but not lgg-1, at the preautophagosomal membrane. Probably, as part of an atg-5-lgg- 3-atg-16 complex, required for lgg-1 lipidation; the comple [...]

atg-9
Autophagy-related protein 9; Involved in autophagy and cytoplasm to vacuole transport (Cvt) vesicle formation. Plays a key role in the organization of the preautophagosomal structure/phagophore assembly site (PAS), the nucleating site for formation of the sequestering vesicle. Belongs to the ATG9 family.

atg-5
Autophagy-related protein 5; Involved in autophagic vesicle formation (By similarity). Conjugation with lgg-3/ATG12, through a ubiquitin-like conjugating system involving atg-7 as an E1-like activating enzyme and atg-10 as an E2-like conjugating enzyme, is essential for its function (By similarity). Most likely a component of an atg-5-lgg-3-atg-16 complex that promotes autophagosome formation by associating with lgg-2, but not lgg-1, at the preautophagosomal membrane. Probably, as part of an atg-5-lgg-3-atg-16 complex, required for lgg-1 lipidation; the complex acts as an E3-like enzym [...]

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.
      
 0.852
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 [...]
      
 0.836
atg-2
Autophagy-related protein 2; Component of the epg-6/atg-2 complex, which is involved in the generation of autophagosomes from omegasomes and in the distribution of atg-9 and atg-13 during the autophagy-mediated degradation of protein aggregates. Involved in autophagy-mediated degradation of ribosomal RNA and ribosomal proteins in lysosomes, which is essential for maintaining nucleotide homeostasis.
