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

Xrcc1
Uncharacterized protein.

polB
DNA polymerase; DNA polymerase that functions in several pathways of DNA repair. Involved in base excision repair (BER) responsible for repair of lesions that give rise to abasic (AP) sites in DNA. Also contributes to DNA double-strand break repair by non-homologous end joining and homologous recombination. Has both template-dependent and template- independent (terminal transferase) DNA polymerase activities. Has also a 5'-deoxyribose-5-phosphate lyase (dRP lyase) activity.

DDB_G0272839
HIT domain-containing protein DDB_G0272839.
    
 
 0.836
dnapkcs
DNA-dependent protein kinase catalytic subunit; Serine/threonine-protein kinase that acts as a molecular sensor for DNA damage. Is recruited to DNA ends by the Ku70/Ku80 heterodimer and is involved in DNA non-homologous end joining (NHEJ) required for double-strand break (DSB) repair and V(D)J recombination (By similarity). This activity is only apparent when DNA damage is administered in G1 phase of the cell cycle. Required for efficient signaling of DNA double-stranded breaks via phosphorylation of H2AX during G1; Belongs to the PI3/PI4-kinase family. DNAPK subfamily.

DDB0192167
Uncharacterized protein.
    
 
 0.806
itpa
Inosine triphosphate pyrophosphatase; Pyrophosphatase that hydrolyzes non-canonical purine nucleotides such as inosine triphosphate (ITP), deoxyinosine triphosphate (dITP) or xanthosine 5'-triphosphate (XTP) to their respective monophosphate derivatives. The enzyme does not distinguish between the deoxy- and ribose forms. Probably excludes non-canonical purines from RNA and DNA precursor pools, thus preventing their incorporation into RNA and DNA and avoiding chromosomal lesions. Belongs to the HAM1 NTPase family.
     
 0.805
lig3
DNA ligase 3; The alpha isoform interacts with DNA-repair protein XRCC1 and can correct defective DNA strand-break repair and sister chromatid exchange following treatment with ionizing radiation and alkylating agents. The beta isoform does not interact with XRCC1 and may be specifically involved in the completion of homologous recombination events that occur during meiotic prophase; Belongs to the ATP-dependent DNA ligase family.
   
 0.796
ku70
ATP-dependent DNA helicase ku70; Involved in non-homologous end joining (NHEJ) DNA double strand break repair.
    
 
 0.789
wrn
ATP-dependent DNA helicase RecQ family protein.
