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

gktProbable tyrosyl-DNA phosphodiesterase; DNA repair enzyme that can remove a variety of covalent adducts from DNA through hydrolysis of a 3'-phosphodiester bond, giving rise to DNA with a free 3' phosphate. Catalyzes the hydrolysis of dead- end complexes between DNA and the topoisomerase I active site tyrosine residue. Hydrolyzes 3'-phosphoglycolates on protruding 3' ends on DNA double-strand breaks due to DNA damage by radiation and free radicals. Acts on blunt-ended double-strand DNA breaks and on single-stranded DNA. May have low 3'exonuclease activity and may be able to remove a sin [...] (580 aa)    
Predicted Functional Partners:
Top1
DNA topoisomerase 1; Releases the supercoiling and torsional tension of DNA introduced during the DNA replication and transcription by transiently cleaving and rejoining one strand of the DNA duplex (By similarity). Introduces a single-strand break via transesterification at a target site in duplex DNA (By similarity). The scissile phosphodiester is attacked by the catalytic tyrosine of the enzyme, resulting in the formation of a DNA-(3'-phosphotyrosyl)-enzyme intermediate and the expulsion of a 5'-OH DNA strand (By similarity). The free DNA strand then undergoes passage around the unb [...]

PNKP
FI07206p; Nucleoside monophosphate kinase activity; double-stranded DNA binding; polynucleotide 3'-phosphatase activity; ATP-dependent polydeoxyribonucleotide 5'-hydroxyl-kinase activity. It is involved in the biological process described with: nucleotide phosphorylation; DNA repair.
   
 
 0.948
CG5316
Aprataxin-like protein; DNA-binding protein involved in single-strand DNA break repair, double-strand DNA break repair and base excision repair. Resolves abortive DNA ligation intermediates formed either at base excision sites, or when DNA ligases attempt to repair non-ligatable breaks induced by reactive oxygen species. Catalyzes the release of adenylate groups covalently linked to 5'-phosphate termini, resulting in the production of 5'-phosphate termini that can be efficiently rejoined (By similarity).
    
 
 0.913
XRCC1
XRCC1 protein; Damaged DNA binding. It is involved in the biological process described with: base-excision repair; single strand break repair.
   
 
 0.899
DNAlig4
DNA ligase 4 (DNAlig4) encodes an ATP-dependent DNA ligase responsible for the sealing of DNA double-strand breaks during the canonical non-homologous end joining pathway of DNA repair. It interacts with the product of XRCC4 for stability and DNA ligase activity.
   
 
 0.884
mus81
EG:BACR7A4.16 protein; Mus81 (mus81) encodes the catalytic subunit of the Mus81-mms4 structure-selective endonuclease that functions in DNA repair.
   
 
 0.871
Ogg1
DNA-(apurinic or apyrimidinic site) lyase; 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. Efficiently incises DNA duplexes containing 8-hydroxyguanine (8-OH-Gua), 8-hydroxyadenine (8- OH-Ade) and abasic (AP) sites placed opposite to a cytosine.

Top2
DNA topoisomerase 2; Control of topological states of DNA by transient breakage and subsequent rejoining of DNA strands. Topoisomerase II makes double-strand breaks. Essential during mitosis and meiosis for proper segregation of daughter chromosomes. During meiosis, it disrupts heterochromatic connections between achiasmate and chiasmate homologs after spindle assembly so that chromosomes can separate at prometaphase I. During mitosis, it functions in the separation of sister chromatids by establishing amphitelic kinetochore attachments in mitotic spindles. May have a role in chromatin [...]

DNAlig3
DNA ligase 3 (DNAlig3) encodes an ATP-dependent DNA ligase that is involved in the repair of nuclear and mitochondrial single- and double-strand DNA breaks.
   
 
 0.846
mei-9
DNA repair endonuclease XPF; Implicated in recombination events during meiosis, mostly in meiotic exchange. May directly resolve Holliday junctions within recombination intermediates leading to DNA exchange. Also required for the repair of mismatches within meiotic heteroduplex DNA and for nucleotide excision repair.
