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

ubql-1Ubiquilin; 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 [...] (502 aa)    
Predicted Functional Partners:
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 [...]

ubq-2
Ubiquitin-60S ribosomal protein L40; [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 invol [...]

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 [...]

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.

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 [...]

rpt-1
26S proteasome regulatory subunit 7; 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).

rpn-13
Proteasomal ubiquitin receptor ADRM1 homolog; May function as a proteasomal ubiquitin receptor. May promote the deubiquitinating activity associated with the 26S proteasome. Belongs to the ADRM1 family.
