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

CG6171Aprataxin and PNK-like factor; Displays apurinic-apyrimidinic (AP) endonuclease and 3'-5' exonuclease activities in vitro. (255 aa)    
Predicted Functional Partners:
Ku80
ATP-dependent DNA helicase II subunit 2; Ku80 (Ku80) encodes a protein that forms a Ku heterodimer with the product of Irbp, which binds to DNA double-strand break ends and is required for the non-homologous end joining pathway of DNA repair.
   
 
 0.971
Irbp
ATP-dependent DNA helicase 2 subunit 1; Single-stranded DNA-dependent ATP-dependent helicase. Involved in non-homologous end joining (NHEJ) DNA double strand break repair (By similarity). Sequence-specific DNA-binding protein that has a high affinity for a 31 bp sequence in the Yp1 gene. Site-specific DNA binding to 31 bp P element inverted repeats.
   
 
 0.932
XRCC1
XRCC1 protein; Damaged DNA binding. It is involved in the biological process described with: base-excision repair; single strand break repair.
   
 
 0.915
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.
    
 
 0.855
CG5664
RE31086p.
   
  
 0.811
CG18596
LP02352p; RNA binding; tRNA (guanine) methyltransferase activity. It is involved in the biological process described with: tRNA methylation.
   
  
 0.795
gkt
Probable 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 [...]

Xpc
DNA repair protein complementing XP-C cells homolog; Involved in DNA excision repair. May play a part in DNA damage recognition and/or in altering chromatin structure to allow access by damage-processing enzymes (By similarity).
   
 
 0.762
Parp
Poly [ADP-ribose] polymerase; Poly-ADP-ribosyltransferase that mediates poly-ADP- ribosylation of proteins and plays a key role in DNA repair. Mainly mediates glutamate and aspartate ADP-ribosylation of target proteins: the ADP-D-ribosyl group of NAD(+) is transferred to the acceptor carboxyl group of glutamate and aspartate residues and further ADP- ribosyl groups are transferred to the 2'-position of the terminal adenosine moiety, building up a polymer with an average chain length of 20-30 units.
    
 
 0.750
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.
