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

ddi-1Protein DDI1 homolog 1; Aspartic protease. Required for the cleavage and activation of transcription factors such as isoform a of the transcription factor skn-1, which in turn regulates the expression of proteasomal subunits such as rpt-3; Belongs to the DDI1 family. (389 aa)    
Predicted Functional Partners:
rad-23

ubq-1
Ubiquitin-related; Ubiquitin exists either covalently attached to another protein, or free (unanchored). When covalently bound, it is conjugated to target proteins via an isopeptide bond either as a monomer (monoubiquitin), a polymer linked via different Lys residues of the ubiquitin (polyubiquitin chains) or a linear polymer linked via the initiator Met of the ubiquitin (linear polyubiquitin chains). Polyubiquitin chains, when attached to a target protein, have different functions depending on the Lys residue of the ubiquitin that is linked: Lys-48-linked is involved in protein degrad [...]

rpn-10
26S proteasome non-ATPase regulatory subunit 4; Binds and presumably selects ubiquitin-conjugates for destruction (By similarity). Required for protein degradation and ubiquitin-proteasome system (UBS) function and regulates proteasomal subunit expression. Involvement in UBS might be cell type specific. Regulator of the autophagy-lysosome pathway that may confer resistance to autophagy by regulating the expression of autophagy-related proteins such as lgg-1, and by regulating lysosome formation, possibly by modulating elt-2 activity. Required for fertility, sperm production, and sex de [...]

rpn-1
26S proteasome non-ATPase regulatory subunit 2; Component of the 26S proteasome, a multiprotein complex involved in the ATP-dependent degradation of ubiquitinated proteins. This complex plays a key role in the maintenance of protein homeostasis by removing misfolded or damaged proteins, which could impair cellular functions, and by removing proteins whose functions are no longer required. Therefore, the proteasome participates in numerous cellular processes, including cell cycle progression, apoptosis, or DNA damage repair; Belongs to the proteasome subunit S2 family.
