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

XRCC4DNA repair protein XRCC4; May be involved in DNA non-homologous end joining (NHEJ) required for double-strand break repair. May bind to DNA. The LIG4- XRCC4 complex is probably responsible for the NHEJ ligation step, and XRCC4 may enhance the joining activity of LIG4 (By similarity). (264 aa)    
Predicted Functional Partners:
LIG4
DNA ligase 4; Efficiently joins single-strand breaks in a double-stranded polydeoxynucleotide in an ATP-dependent reaction. Involved in DNA non- homologous end joining (NHEJ) required for double-strand break repair. May be involved for T-DNA integration even if not absolutely required. Seems to be dispensable under normal growth conditions. Belongs to the ATP-dependent DNA ligase family.

KU70
ATP-dependent DNA helicase 2 subunit KU70; Single-stranded DNA-dependent ATP-dependent helicase. Involved in DNA non-homologous end joining (NHEJ) required for double- strand break repair. When associated with KU80, binds to double- stranded telomeric and non-telomeric DNA sequences, but not to single- stranded DNA. Plays a role in maintaining telomere length. Acts as a negative regulator of telomerase. Required for maintenance of the telomeric C-rich strand. Belongs to the ku70 family.

BHLH140
Transcription factor bHLH140.
   
 
 0.996
KU80
ATP-dependent DNA helicase 2 subunit KU80; Single-stranded DNA-dependent ATP-dependent helicase. Involved in DNA non-homologous end joining (NHEJ) required for double- strand break repair. When associated with KU70, binds to double- stranded telomeric and non-telomeric DNA sequences, but not to single- stranded DNA. Plays a role in maintaining telomere length. Acts as a negative regulator of telomerase. Binds to and recombines double- stranded T-DNA molecules. Belongs to the ku80 family.

LIG1
DNA ligase 1; Essential protein. DNA ligase that seals nicks in double- stranded DNA during DNA replication, DNA recombination and DNA repair. Involved in repair of both single strand breaks (SSBs) and double strand breaks (DSBs). Required in the endosperm for embryogenesis, probably to repair DNA-breaks generated by DME.
    
 0.959
POLL
DNA polymerase lambda; Repair polymerase involved in base excision repair (BER) and responsible for repair of lesions that give rise to abasic (AP) sites in DNA. Has both DNA polymerase and terminal transferase activities. Has a 5'-deoxyribose-5-phosphate lyase (dRP lyase) activity (By similarity). Involved in the repair of transposon-induced DNA double strand breaks (DSBs). Involved in repair of UV-B- mediated DNA damage during seedling development through an excision repair mechanism. Involved the repair of DSBs induced by high salinity and DNA cross-linking agent. Functions via the [...]

F13F21.31
DNA ligase.
    
 0.940
XRCC1
DNA-repair protein XRCC1; Corrects defective DNA strand-break repair and sister chromatid exchange following treatment with ionizing radiation and alkylating agents (By similarity). Involved in DNA demethylation pathway by stimulating cytosine methylation (5-meC) excision, gap tailoring, and DNA ligation.
      
 0.939
LIG6
DNA ligase 6; DNA ligase that seals nicks in double-stranded DNA during DNA replication, DNA recombination and DNA repair (Probable). Required to maintain seed viability (e.g. longevity and storability) and during seed germination, probably by repairing DNA damage accumulated during seed development, storage and/or imbibition. Facilitates seed germination in cold conditions (2 degrees Celsius) and under oxidative stress (e.g. menadione, a genotoxic agent). Involved in repair of X- ray-induced damage ; Belongs to the ATP-dependent DNA ligase family.
    
 0.938
ERCC1
DNA excision repair protein ERCC-1; Seems to be involved in nucleotide excision repair (NER) of damaged DNA (dark repair mechanism). The UVH1/RAD1-ERCC1/RAD10 complex may act as an endonuclease making DNA incision 5' to the lesion site. In vitro, is implicated in double strand breaks (DSBs) repair and is required for homologous recombination in the presence of non-homologous overhangs. In vitro, is involved in chromosomal recombination between tandem repeats in both direct and inverted orientations. May mediate the induction of a DNA-damage sensitive cell-cycle checkpoint during the G2 [...]
