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

DNApol-thetaDNA polymerase theta; Multifunctional protein with both DNA polymerase and ATPase activities. Might have 3' to 5' exonuclease activity. Plays a role in different DNA repair pathways such as DNA strand cross-link repair and microhomology- mediated end-joining (MMEJ), an alternative non-homologous end-joining (NHEJ) machinery triggered in response to double-strand breaks. MMEJ is an error- prone repair pathway that produces deletions of sequences from the strand being repaired and promotes genomic rearrangements, such as telomere fusions. Utilizes short microhomologies present in partial [...] (2059 aa)    
Predicted Functional Partners:
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.

DNApol-zeta
DNA polymerase zeta catalytic subunit; As the catalytic subunit of the DNA polymerase zeta complex, plays a crucial role in translesion DNA synthesis (TLS) and various DNA repair mechanisms. Lacks an intrinsic 3'-5' exonuclease activity and thus has no proofreading function. During homologous recombination (HR) repair, has a overlapping role with the error-prone translesion polymerase eta to initiate repair synthesis which is completed by end joining or another polymerase that can bind and reinitiate synthesis. May participate in the Rrp1- dependent base excision repair (BER) pathway r [...]

spn-A
DNA repair protein Rad51 homolog; Spindle A (spn-A) encodes a protein that forms a filament on single-stranded DNA, does a homology search of double-stranded DNA, and catalyzes strand exchange, swapping the single-strand DNA in and displacing the partner of the complementary strand.

mus201
Mutagen-sensitive 201 (mus201) encodes a protein involved in UV-damage excision repair.

tos
Exonuclease 1; 5'->3' double-stranded DNA exonuclease which may also contain a cryptic 3'->5' double-stranded DNA exonuclease activity. Also exhibits endonuclease activity against 5'-overhanging flap structures similar to those generated by displacement synthesis when DNA polymerase encounters the 5'-end of a downstream Okazaki fragment. Required for DNA mismatch repair (MMR) (By similarity).

Fen1
Flap endonuclease 1; Structure-specific nuclease with 5'-flap endonuclease and 5'- 3' exonuclease activities involved in DNA replication and repair. During DNA replication, cleaves the 5'-overhanging flap structure that is generated by displacement synthesis when DNA polymerase encounters the 5'-end of a downstream Okazaki fragment. It enters the flap from the 5'-end and then tracks to cleave the flap base, leaving a nick for ligation. Also involved in the long patch base excision repair (LP-BER) pathway, by cleaving within the apurinic/apyrimidinic (AP) site- terminated flap. Acts as [...]

CG44774
Uncharacterized protein, isoform C; It is involved in the biological process described with: negative regulation of cell migration.

mre11
Double-strand break repair protein; 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.
   
 0.818
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.
