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

DNApol-etaDNApol-eta; DNA polymerase specifically involved in the DNA repair by translesion synthesis (TLS). Plays an important role in translesion synthesis, where the normal high-fidelity DNA polymerases cannot proceed and DNA synthesis stalls. Inserts one or 2 nucleotide(s) opposite the lesion. During homologous recombination (HR) repair, has a overlapping role with the error-prone translesion polymerase DNApol-zeta/DNApolZ1 to initiate repair synthesis that is completed by end joining or another polymerase that can bind and reinitiate synthesis. Particularly important for the repair of UV-in [...] (885 aa)    
Predicted Functional Partners:
Rev1
DNA repair protein Rev1; Deoxycytidyl transferase involved in DNA repair. Transfers a dCMP residue from dCTP to the 3'-end of a DNA primer in a template-dependent reaction. May assist in the first step in the bypass of abasic lesions by the insertion of a nucleotide opposite the lesion. Required for normal induction of mutations by physical and chemical agents (By similarity). During homologous recombination (HR) repair of DNA double-strand breaks (DSBs) regulates the extent of repair synthesis. Possibly recruits the DNA polymerase zeta complex or another translesion polymerase to earl [...]

DNApol-zeta
DNA polymerase zeta catalytic subunit; As the catalytic subunit of the DNA polymerase zeta complex, plays a crucial role in translesion DNA synthesis (TLS) and various DNA repair mechanisms. Lacks an intrinsic 3'-5' exonuclease activity and thus has no proofreading function. During homologous recombination (HR) repair, has a overlapping role with the error-prone translesion polymerase eta to initiate repair synthesis which is completed by end joining or another polymerase that can bind and reinitiate synthesis. May participate in the Rrp1- dependent base excision repair (BER) pathway r [...]

PCNA2
Proliferating cell nuclear antigen 2; Likely to be an auxiliary protein of DNA polymerase delta complex and is probably involved in the control of DNA replication and repair by increasing the polymerase's processibility. May function independently of PCNA during DNA repair.
   
 
 0.964
PCNA
Proliferating cell nuclear antigen; Likely to be an auxiliary protein of DNA polymerase delta complex and is probably involved in the control of DNA replication and repair by increasing the polymerase's processibility. Belongs to the PCNA family.
   
 0.960
Rev7
DNA polymerase zeta processivity subunit; As the accessory component of the DNA polymerase zeta complex, involved in translesion DNA synthesis (TLS) and various DNA repair mechanisms. Promotes the apurinic/apyrimidinic (AP) endonuclease activity of Rrp1 and is therefore likely to be involved in the base excision repair (BER) pathway responsible for repair of DNA lesions. It does not appear to influence the synthesis activity of the catalytic component Dmpol-zeta.
   
 
 0.942
Rchy1
Ring finger and CHY zinc finger domain containing 1, isoform A; Ubiquitin protein ligase activity; zinc ion binding; ubiquitin-protein transferase activity. It is involved in the biological process described with: ubiquitin-dependent protein catabolic process; negative regulation of gliogenesis; protein ubiquitination.
    
 0.941
DNApol-delta
DNA polymerase delta catalytic subunit; As the catalytic component of the DNA polymerase delta complex, plays a crucial role in high fidelity genome replication, including lagging strand synthesis, DNA recombination and repair (By similarity). Exhibits both DNA polymerase and 3'- to 5'-exonuclease activities. Required at the nucleus of rapidly dividing embryonic cells to activate genome replication during the earliest cell cycles. Likely to require the presence of accessory proteins Pol31 and Pol32 for full activity.

Uev1A
Ubiquitin-conjugating enzyme variant 1A (Uev1A) encodes a conserved protein that contributes to ubiquitin conjugating enzyme activity, but not catalytically, since it lacks the conserved cysteine residue essential for ubiquitin conjugation. It regulates genomic integrity, IMD pathway-mediated innate immunity, JNK-pathway mediated cell death and tumor invasion.
   
 
 0.862
spn-A
DNA repair protein Rad51 homolog; Spindle A (spn-A) encodes a protein that forms a filament on single-stranded DNA, does a homology search of double-stranded DNA, and catalyzes strand exchange, swapping the single-strand DNA in and displacing the partner of the complementary strand.
  
 
 0.853
RpS27A
Ubiquitin-40S ribosomal protein S27a; 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 involve [...]
