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:
some 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 each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

UNG1Uracil-DNA glycosylase, required for repair of uracil in DNA formed by spontaneous cytosine deamination, not required for strand-specific mismatch repair, cell-cycle regulated, expressed in late G1, localizes to mitochondria and nucleus; Excises uracil residues from the DNA which can arise as a result of misincorporation of dUMP residues by DNA polymerase or due to deamination of cytosine. Not involved in strand-directed mismatch repair (359 aa)    
Predicted Functional Partners:
POL30
Proliferating cell nuclear antigen (PCNA), functions as the sliding clamp for DNA polymerase delta; may function as a docking site for other proteins required for mitotic and meiotic chromosomal DNA replication and for DNA repair; This protein is an auxiliary protein of DNA polymerase delta and is involved in the control of eukaryotic DNA replication by increasing the polymerase’s processibility during elongation of the leading strand. Involved in DNA repair (258 aa)
     
 
  0.997
DUT1
Deoxyuridine triphosphate diphosphatase (dUTPase); catalyzes hydrolysis of dUTP to dUMP and PPi, thereby preventing incorporation of uracil into DNA during replication; critical for the maintenance of genetic stability; also has diphosphatase activi /.../deoxyinosine triphosphate; This enzyme is involved in nucleotide metabolism- it produces dUMP, the immediate precursor of thymidine nucleotides and it decreases the intracellular concentration of dUTP so that uracil cannot be incorporated into DNA (147 aa)
   
 
  0.986
APN1
Major apurinic/apyrimidinic endonuclease, 3’-repair diesterase involved in repair of DNA damage by oxidation and alkylating agents; also functions as a 3’-5’ exonuclease to repair 7,8-dihydro-8-oxodeoxyguanosine; DNA repair enzyme that cleaves apurinic/apyrimidinic (AP) sites and removes 3’-blocking groups present at single strand breaks of damaged DNA. APN1 accounts for > 97% of both apurinic/ apyrimidinic (AP) lyase and DNA 3’-repair diesterase activities (367 aa)
   
 
  0.936
OGG1
Mitochondrial glycosylase/lyase that specifically excises 7,8-dihydro-8-oxoguanine residues located opposite cytosine or thymine residues in DNA, repairs oxidative damage to mitochondrial DNA, contributes to UVA resistance; DNA repair enzyme that incises DNA at 8-oxoG residues. Excises 7,8-dihydro-8-oxoguanine and 2,6-diamino-4-hydroxy-5-N- methylformamidopyrimidine (FAPY) from damaged DNA. Has a beta- lyase activity that nicks DNA 3’ to the lesion (376 aa)
   
   
  0.936
SLX1
Subunit of a complex, with Slx4p, that hydrolyzes 5’ branches from duplex DNA in response to stalled or converging replication forks; function overlaps with that of Sgs1p-Top3p; Catalytic subunit of the SLX1-SLX4 structure-specific endonuclease that resolves DNA secondary structures generated during DNA repair and recombination. Has endonuclease activity towards branched DNA substrates, introducing single-strand cuts in duplex DNA close to junctions with ss-DNA. Has a preference for simple Y, 5’-flap and replication fork-like structures. It cleaves the strand bearing the 5’-non-homolog [...] (304 aa)
           
  0.923
CDC9
DNA ligase found in the nucleus and mitochondria, an essential enzyme that joins Okazaki fragments during DNA replication; also acts in nucleotide excision repair, base excision repair, and recombination; DNA ligase that seals nicks in double-stranded DNA during DNA replication, DNA recombination and DNA repair. The mitochondrial form is required for mitochondrial DNA maintenance but is non-essential while the nuclear form is essential for cell viability (755 aa)
     
   
  0.916
APN2
Class II abasic (AP) endonuclease involved in repair of DNA damage; homolog of human HAP1 and E. coli exoIII; DNA repair enzyme that cleaves apurinic/apyrimidinic (AP) sites and removes 3’-blocking groups present at single strand breaks of damaged DNA (520 aa)
     
 
  0.904
CDC21
Thymidylate synthase, required for de novo biosynthesis of pyrimidine deoxyribonucleotides; expression is induced at G1/S; Thymidylate synthase required for de novo biosynthesis of pyrimidine deoxyribonucleotides. Required for both nuclear and mitochondrial DNA synthesis (304 aa)
   
 
  0.876
RFA2
Subunit of heterotrimeric Replication Protein A (RPA), which is a highly conserved single-stranded DNA binding protein involved in DNA replication, repair, and recombination; Binds to single-stranded sequences participating in DNA replication in addition to those mediating transcriptional repression (URS1) and activation (CAR1). Stimulates the activity of a cognate strand exchange protein (SEP1). It cooperates with T- AG and DNA topoisomerase I to unwind template DNA containing the simian virus 40 origin of DNA replication (273 aa)
     
 
  0.866
MSH6
Protein required for mismatch repair in mitosis and meiosis, forms a complex with Msh2p to repair both single-base & insertion-deletion mispairs; potentially phosphorylated by Cdc28p; Component of the post-replicative DNA mismatch repair system (MMR). Heterodimerizes with MSH2 to form MutS alpha, which binds to DNA mismatches thereby initiating DNA repair. MSH6 provides substrate-binding and substrate specificity to the complex. When bound, MutS alpha bends the DNA helix and shields approximately 20 base pairs. Acts mainly to repair base-base and single insertion-deletion mismatches th [...] (1242 aa)
