STRINGSTRING
KU80 protein (Arabidopsis thaliana) - STRING interaction network
"KU80" - ATP-dependent DNA helicase 2 subunit KU80 in Arabidopsis thaliana
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

KU80ATP-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 (680 aa)    
Predicted Functional Partners:
KU70
KU70 homolog; 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 (621 aa)

ATLIG4
DNA ligase 4; Efficiently joins single-strand breaks in a double- stranded polydeoxynucleotide in an ATP-dependent reaction. Involved in DNA nonhomologous 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 (1219 aa)
     
  0.999
RAD50
DNA repair protein RAD50; Implicated in double-strand breaks (DSBs) repair by non- homologous end joining (NHEJ). Involved in telomere maintenance. Involved in telomerase action on chromosome ends. Required during meiosis for both male and female gametophytic development, for pairing and synapsis of homologous chromosomes during the early stages of meiotic recombination, especially during the pachytene stage of the first division (1316 aa)
     
 
  0.994
MRE11
MEIOTIC RECOMBINATION 11; Involved in DNA double-strand break repair (DSBR). Possesses single-strand endonuclease activity and double-strand- specific 3’-5’ exonuclease activity. Also involved in meiotic DSB processing (By similarity) (720 aa)
     
 
  0.994
LIG6
DNA LIGASE 6 (1396 aa)
     
  0.993
TERT
Telomerase reverse transcriptase; Telomerase is a ribonucleoprotein enzyme essential for the replication of chromosome termini in most eukaryotes. It elongates telomeres. It is a reverse transcriptase that adds simple sequence repeats to chromosome ends by copying a template sequence within the RNA component of the enzyme. Required to prevent genome instability induced by breakage-fusion-bridge (BFB) cycles. Can extend completely non-telomeric sequences using RNA template in vitro (1123 aa)
     
  0.988
RFC1
Replication factor C1; Plays a role as mediator of transcriptional gene silencing (TGS), DNA replication, DNA repair, hypersensitive response (HR) and telomere length regulation. Is required in meiosis for DNA double-strand break (DSB) repair during meiotic homologous recombination. May participate in the RAD51-mediated recombination intermediate repair process. Is important for lagging strand synthesis. Promotes meiotic recombination via a specific pathway for crossovers (COs) that involves the formation of double Holliday Junction (dHJ) intermediates (956 aa)
     
 
  0.979
ATM
Ataxia-telangiectasia mutated; Serine/threonine protein kinase which activates checkpoint signaling upon genotoxic stresses such as ionizing radiation (IR) or DNA replication stalling. Plays a central role in the perception and response to both stress-induced damage in somatic cells and developmentally programmed DNA damage during meiosis. Recognizes the substrate consensus sequence [ST]-Q. Phosphorylates histone variant H2AX to form H2AXS139ph at double strand breaks (DSBs), thereby regulating DNA damage response mechanism. Involved in transcriptional regulation of RAD51, PARP1, GR1, [...] (3845 aa)
     
 
  0.978
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 (790 aa)
     
  0.966
AT3G14890
Phosphoesterase; Nick-sensing 3’-phosphoesterase involved in a base excision repair pathway required for active DNA demethylation. The N-terminal DNA-binding domain binds specifically to gap sites and sharply bends the target DNA. Lacks 5’-kinase activity but is capable of 3’-phosphoglycolate end processing. Inactive on 3’- alpha,beta-unsaturated aldehyde (3’-dRP). Protects partially genes from transcriptional silencing by preventing promoter DNA hypermethylation (694 aa)
