STRINGSTRING
TDP1 protein (Saccharomyces cerevisiae) - STRING interaction network
"TDP1" - Tyrosyl-DNA Phosphodiesterase I, hydrolyzes 3' and 5'-phosphotyrosyl bonds, involved in the repair of DNA lesions created by topoisomerase I and topoisomerase II in Saccharomyces cerevisiae
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

TDP1Tyrosyl-DNA Phosphodiesterase I, hydrolyzes 3’ and 5’-phosphotyrosyl bonds, involved in the repair of DNA lesions created by topoisomerase I and topoisomerase II; mutations in human homolog result in the neurodegenerative disease SCANI; 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 b [...] (544 aa)    
Predicted Functional Partners:
MRE11
Subunit of a complex with Rad50p and Xrs2p (MRX complex) that functions in repair of DNA double-strand breaks and in telomere stability, exhibits nuclease activity that appears to be required for MRX function; widely conserved; 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 (692 aa)

TOP1
Topoisomerase I, nuclear enzyme that relieves torsional strain in DNA by cleaving and re-sealing the phosphodiester backbone; relaxes both positively and negatively supercoiled DNA; functions in replication, transcription, and recombination; 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, r [...] (769 aa)

APN2
Class II abasic (AP) endonuclease involved in repair of DNA damage; homolog of human HAP1 and E. coli exoIII; DNA repair enzyme that cleaves apurinic/apyrimidinic (AP) sites and removes 3’-blocking groups present at single strand breaks of damaged DNA (520 aa)
     
 
  0.931
MUS81
Subunit of the structure-specific Mms4p-Mus81p endonuclease that cleaves branched DNA; involved in DNA repair, replication fork stability, and joint molecule formation/resolution during meiotic recombination; helix-hairpin-helix protein; Interacts with MMS4 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 with regressed leading strands and nicked Holliday junctions. Cleavage probably occurs approximately half a helical turn upst [...] (632 aa)

RAD10
Single-stranded DNA endonuclease (with Rad1p), cleaves single-stranded DNA during nucleotide excision repair and double-strand break repair; subunit of Nucleotide Excision Repair Factor 1 (NEF1); homolog of human ERCC1 protein; Involved in nucleotide excision repair of DNA damaged with UV light, bulky adducts, or cross-linking agents.

POL4
DNA polymerase IV, undergoes pair-wise interactions with Dnl4p-Lif1p and Rad27p to mediate repair of DNA double-strand breaks by non-homologous end joining (NHEJ); homologous to mammalian DNA polymerase beta; Repair polymerase. Involved in gap-filling in DNA nonhomologous end joining (NHEJ) required for double-strand break repair. Seems to conduct DNA synthesis in a stepwise distributive fashion rather than in a processive fashion as for other DNA polymerases. Preferentially acts upon short gaps formed by the alignment of linear duplexes with complementary single-strand ends. Required [...] (582 aa)
