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

png-1Peptide-N(4)-(N-acetyl-beta-glucosaminyl)asparagine amidase; Specifically deglycosylates the denatured form of N-linked glycoproteins in the cytoplasm and assists their proteasome-mediated degradation. Cleaves the beta- aspartyl-glucosamine (GlcNAc) of the glycan and the amide side chain of Asn, converting Asn to Asp. Prefers proteins containing high-mannose over those bearing complex type oligosaccharides. Can recognize misfolded proteins in the endoplasmic reticulum that are exported to the cytosol to be destroyed and deglycosylate them, while it has no activity toward native protein [...] (606 aa)    
Predicted Functional Partners:
rad-23
Uncharacterized protein.
   
 0.995
rps-30
40S ribosomal protein S30; Belongs to the eukaryotic ribosomal protein eS30 family.
   
 
 0.889
cup-2
Derlin-1; Specifically required for the degradation process of misfolded endoplasmic reticulum (ER) luminal proteins. Participates in the transfer of misfolded proteins from the ER to the cytosol, where they are destroyed by the proteasome in a ubiquitin-dependent manner. Belongs to the derlin family.
   
 0.877
hrdl-1
E3 ubiquitin-protein ligase hrd-like protein 1; Proposed to have a role in neuroprotection.
   
 0.873
cdc-48.2
Transitional endoplasmic reticulum ATPase homolog 2; ATP-dependent chaperone which probably uses the energy provided by ATP hydrolysis to generate mechanical force to unfold substrate proteins, disassemble protein complexes, and disaggregate protein aggregates. However, able to prevent aggregation of unfolded proteins also in an ATP-independent manner. Targets polyubiquitinated proteins for proteasomal degradation by binding to 'Lys-48'-linked polyubiquitin chains. Involved in the cytoplasmic elimination of misfolded proteins exported from the ER. This pathway, known as ERAD, prevents [...]
  
 0.862
rpt-2
Probable 26S proteasome regulatory subunit 4; The 26S proteasome is involved in the ATP-dependent degradation of ubiquitinated proteins. The regulatory (or ATPase) complex confers ATP dependency and substrate specificity to the 26S complex (By similarity). May play a role in the degradation of microtubule severing protein mei-1.
   
 0.862
ubxn-1
UBX domain-containing protein 1; Ubiquitin-binding protein which acts as an adapter for ATPase cdc-48.1 and/or cdc-48.2, conferring substrate specificity. Together with ubxn-2 and ubxn-3, plays a role in hermaphrodite spermatogenesis probably by promoting the degradation of sex determination terminal factor tra-1.
   
 0.851
ubql-1
Ubiquilin; May play a role in the ER-associated protein degradation pathway (ERAD) possibly via its interaction with ER-localized proteins ubxn-4 and cdc-48.1 and/or cdc48.2, providing a link between the polyubiquitinated ERAD substrates and the proteasome. Also plays an important role in the regulation of other protein degradation mechanisms and pathways including ubiquitin-proteasome system (UPS) and autophagy (By similarity). Mediates the proteasomal targeting of misfolded or accumulated proteins for degradation by binding (via UBA domain) to their polyubiquitin chains and by intera [...]

Y73B6BL.12
Thioredoxin; Belongs to the thioredoxin family.
  
 
 0.767
ufd-2
Ubiquitin conjugation factor E4 ufd-2; Acts as an E4 ubiquitin ligase mediating the assembly of polyubiquitin chains on substrates ubiquitinated by another E3 ubiquitin ligase. The elongation of preexisting ubiquitin chains preferentially targets ubiquitin 'Lys-29' and 'Lys-48' residues. Also functions as an E3 ligase in conjunction with specific E1 and E2 ligases. Probably by regulating protein ubiquitination at DNA damage repair sites, coordinates DNA double- strand-break repair and apoptosis in the germline. Required for germline apoptosis in response to DNA damage downstream of cep [...]
