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

let-70Ubiquitin-conjugating enzyme E2 2; Catalyzes the covalent attachment of ubiquitin to other proteins (By similarity). Mediates the selective degradation of short- lived and abnormal proteins. Plays a role in the DNA damage response. In particular, in response to ionizing radiation, associates with the E3 ubiquitin-protein ligase brc-1-brd-1 heterodimer on chromatin to activate E3-ubiquitin ligase activity of the heterodimer, and thus its DNA damage repair mechanisms ; Belongs to the ubiquitin-conjugating enzyme family. (147 aa)    
Predicted Functional Partners:
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 [...]

uba-1
UBA_e1_C domain-containing protein; Belongs to the ubiquitin-activating E1 family.
  
 0.990
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 [...]
   
 0.990
otub-1
Ubiquitin thioesterase otubain-like; Hydrolase that can remove conjugated ubiquitin from proteins and plays an important regulatory role at the level of protein turnover by preventing degradation. Specifically cleaves 'Lys-48'-linked polyubiquitin.
   
 0.984
apc-11
Anaphase-promoting complex subunit 11; Probable component of the anaphase promoting complex/cyclosome (APC/C), a cell cycle-regulated E3 ubiquitin ligase that controls progression through mitosis and the G1 phase of the cell cycle. The APC/C complex acts by mediating ubiquitination and subsequent degradation of target proteins. Developmental role in early embryogenesis and the metaphase to anaphase transition in meiosis and mitosis. In vitro, recruits the ubiquitin-conjugating enzyme ubc-2 to exert ubiquitin ligase activity. Belongs to the RING-box family.
    
 
 0.968
uev-1
Ubiquitin-conjugating enzyme E2 variant 1; Involved in protein ubiquitination, but has no ubiquitin ligase activity on its own. The uev-1-ubc-13 heterodimer catalyzes the synthesis of non-canonical poly-ubiquitin chains that are linked through Lys-63. Involved in sorting Lys-63-linked polyubiquitinated maternal membrane proteins for degradation by targeting to multivesicular bodies. Required for glr-1-containing glutamate receptor trafficking in neurons. May have a role in synaptic transmission at motorneurons. May be involved in the ubiquitination and growth of intracellular polygluta [...]
   
0.951
rbx-1
RING-box protein 1; Component of the SCF (SKP1-CUL1-F-box protein) E3 ubiquitin ligase complex, which mediates the ubiquitination and subsequent proteasomal degradation of target proteins. Through the RING-type zinc finger, seems to recruit the E2 ubiquitination enzyme to the complex and brings it into close proximity to the substrate (By similarity). Essential for meiosis, mitotic chromosomal condensation and cytokinesis. Involved in histone H3 phosphorylation.
   
 0.945
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 [...]
