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

MUS81Crossover 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, nicked Holliday junctions and also intact Holliday junctions with a reduced efficiency. May be required in mitosis for the processing of stalled or collapsed replication fork intermediates. Plays a role in DNA repair and in genotoxic stress-induced homologous recombination (HR) in somatic cells. Mediates a subset of meioti [...] (659 aa)    
Predicted Functional Partners:
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 [...]

UVH1
DNA repair endonuclease UVH1; Seems to be involved in nucleotide excision repair (NER) of damaged DNA (dark repair mechanism). Involved in repair of UV light, and probably oxidative damage. 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. May mediate the induction of a DNA-damage sensitive cell- cycle checkpoint during the G2 phase.

TOP3A
DNA topoisomerase 3-alpha; 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-(5'-phosphotyrosyl)- enzyme intermediate and the expulsion of a 3'-OH DNA strand. The free DNA strand then undergoes passage around the unbroken strand thus removing DNA supercoils [...]

FANCM
DEAD-box ATP-dependent RNA helicase FANCM; Involved in ordered homologous recombination (HR) events in somatic and meiotic cells. Involved in the suppression of spontaneous HR events in somatic cells. Has an opposite function to the DNA binding cofactor MHF1 which promotes spontaneous HR. Functions in replicative repair independently of MHF1 and in a parallel pathway to the endonuclease MUS81. Acts in the same pathway as the two DNA- binding cofactors MHF1 and MHF2 to restrain class II meiotic crossover (CO), and acts exclusively with MHF1 and MHF2 during meiosis to repair DNA interstr [...]

UVH3
DNA repair protein UVH3; Putative single-stranded DNA endonuclease involved in nucleotide excision repair (NER) of UV- and oxidative damaged DNA. May make the 3'-incision step in NER. Seems to play a role in senescence program; Belongs to the XPG/RAD2 endonuclease family. XPG subfamily.
   
 0.986
MSH4
DNA mismatch repair protein MSH4; Involved in meiotic recombination in association with MSH5. Required for reciprocal recombination and proper segregation of homologous chromosomes at meiosis. Promotes homologous recombination through facilitating chiasma formation during prophase I. Involved in the control of class I crossovers formation. Belongs to the DNA mismatch repair MutS family.

RECQL4A
ATP-dependent DNA helicase Q-like 4A; 3'-5' DNA helicase involved in DNA repair. Required for the maintenance of genome stability by modulation of the DNA damage response and repression of crossovers. Confers resistance to genotoxic stress. Suppresses spontaneous homologous recombination (HR) events in somatic cells together with its partners RMI1 and TOP3A. Contributes to the maintenance of chromosome integrity during meiosis. Involved in the removal of telomeric bridges that appear to arise during meiotic recombination. Required to resolve or dissolve MSH4-dependent telomeric associa [...]

EXO1
Exonuclease 1; Putative 5'->3' double-stranded DNA exonuclease which may also contain a cryptic 3'->5' double-stranded DNA exonuclease activity. May be involved in DNA mismatch repair (MMR) (By similarity). Belongs to the XPG/RAD2 endonuclease family. EXO1 subfamily.
