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

tdp1Probable 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 [...] (536 aa)    
Predicted Functional Partners:
top1
DNA topoisomerase 1; Releases the supercoiling and torsional tension of DNA introduced during the DNA replication and transcription by transiently cleaving and rejoining one strand of the DNA duplex. Introduces a single-strand break via transesterification at a target site in duplex DNA. The scissile phosphodiester is attacked by the catalytic tyrosine of the enzyme, resulting in the formation of a DNA-(3'-phosphotyrosyl)- enzyme intermediate and the expulsion of a 5'-OH DNA strand. TThe free DNA strand then rotates around the intact phosphodiester bond on the opposing strand, thus rem [...]

pnk1
Bifunctional polynucleotide phosphatase/kinase; Catalyzes the phosphorylation of DNA at 5'-hydroxyl termini and can dephosphorylate its 3'-phosphate termini. Has a role in the repair of breaks in single-stranded DNA; In the N-terminal section; belongs to the DNA 3' phosphatase family.
   
 
 0.968
hnt3
Aprataxin-like protein; DNA-binding protein involved in single-strand DNA break repair, double-strand DNA break repair and base excision repair. Resolves abortive DNA ligation intermediates formed either at base excision sites, or when DNA ligases attempt to repair non-ligatable breaks induced by reactive oxygen species. Catalyzes the release of adenylate groups covalently linked to 5'-phosphate termini, resulting in the production of 5'- phosphate termini that can be efficiently rejoined. Likewise, catalyzes the release of 3'-linked guanosine (DNAppG) and inosine (DNAppI) from DNA, bu [...]

apn2
DNA-(apurinic or apyrimidinic site) lyase 2; DNA repair enzyme that cleaves apurinic/apyrimidinic (AP) sites and removes 3'-blocking groups present at single strand breaks of damaged DNA. Provides the majority of the AP-endonuclease (APE) activity. Repairs phleomycin D1-induced DNA damage. Plays a role in oxidative damage repair; Belongs to the DNA repair enzymes AP/ExoA family.
   
 
 0.947
top2
DNA topoisomerase 2; Control of topological states of DNA by transient breakage and subsequent rejoining of DNA strands. Topoisomerase II makes double- strand breaks.
   
 
 0.927
swi10
Mating-type switching protein swi10; Involved in termination of copy-synthesis during mating-type switching. Involved in nucleotide excision repair of DNA damaged with UV light, bulky adducts, or cross-linking agents. Along with RAD16 forms an endonuclease that specifically degrades single-stranded DNA; Belongs to the ERCC1/RAD10/SWI10 family.
   
 
 0.919
rad16
DNA repair protein rad16; Endonuclease that specifically degrades single-stranded DNA and which is involved in nucleotide excision repair of DNA damaged with UV light, bulky adducts, or cross-linking agents. Required for double strand break-induced interchromosomal gene conversion. Belongs to the XPF family.
   
 
 0.905
mus81
Crossover junction endonuclease mus81; Interacts with eme1 to form a DNA structure-specific endonuclease with substrate preference for branched DNA structures with a 5'-end at the branch nick. Typical substrates include 3'-flap structures, D-loops, replication forks and nicked Holliday junctions. May be required in mitosis for the processing of stalled or collapsed replication fork intermediates. May be required in meiosis for the repair of meiosis-specific double strand breaks subsequent to single- end invasion (SEI). Belongs to the XPF family.

lig4
DNA ligase 4; Involved in ds DNA break repair. Belongs to the ATP-dependent DNA ligase family.
   
 
 0.867
adl1
DNA ligase 3; Belongs to the ATP-dependent DNA ligase family.
