STRINGSTRING
SLX4 protein (Saccharomyces cerevisiae) - STRING interaction network
"SLX4" - Endonuclease involved in processing DNA during recombination and repair 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

SLX4Endonuclease involved in processing DNA during recombination and repair; cleaves branched structures in a complex with Slx1p; involved in Rad1p/Rad10p-dependent removal of 3’-nonhomologous tails during DSBR via single-strand annealing; Regulatory subunit that interacts with and increases the activity of different structure-specific endonucleases. Has several distinct roles in protecting genome stability by resolving diverse forms of deleterious DNA structures. Component of the SLX1-SLX4 structure-specific endonuclease that resolves DNA secondary structures generated during DNA repair a [...] (748 aa)    
Predicted Functional Partners:
SLX1
Subunit of a complex, with Slx4p, that hydrolyzes 5’ branches from duplex DNA in response to stalled or converging replication forks; function overlaps with that of Sgs1p-Top3p; Catalytic subunit of the SLX1-SLX4 structure-specific endonuclease that resolves DNA secondary structures generated during DNA repair and recombination. Has endonuclease activity towards branched DNA substrates, introducing single-strand cuts in duplex DNA close to junctions with ss-DNA. Has a preference for simple Y, 5’-flap and replication fork-like structures. It cleaves the strand bearing the 5’-non-homolog [...] (304 aa)

RTT107
Protein implicated in Mms22-dependent DNA repair during S phase; involved in recruiting the SMC5/6 complex to double-strand breaks; DNA damage induces phosphorylation by Mec1p at one or more SQ/TQ motifs; interacts with Mms22p and Slx4p; has four BR /.../ains; has a role in regulation of Ty1 transposition; Required for resumption of chromosome replication after DNA damage, specifically in S phase. Is recruited to chromatin in the presence of RTT109 and RTT101 in response to stalled replication forks and acts as a scaffold during DNA repair (1070 aa)

SGS1
Nucleolar DNA helicase of the RecQ family; involved in genome integrity maintenance; regulates chromosome synapsis and meiotic joint molecule/crossover formation; potential role as repressor of a subset of rapamycin responsive genes; rapidly lost in /.../nse to rapamycin in Rrd1p-dependent manner; similar to human BLM and WRN proteins implicated in Bloom and Werner syndromes; ATP-dependent DNA helicase able to unwind duplex DNA or DNA- RNA heteroduplex (PubMed-9545297). Displacement of the DNA strand occurs in the 3’ to 5’ direction with respect to the single-stranded DNA flanking the [...] (1447 aa)

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)

RAD51
Strand exchange protein, forms a helical filament with DNA that searches for homology; involved in the recombinational repair of double-strand breaks in DNA during vegetative growth and meiosis; homolog of Dmc1p and bacterial RecA protein; Required both for recombination and for the repair of DNA damage caused by X-rays. Its function may be modulated by interaction with other repair proteins. RAD52 interacts directly with RAD51, via its C-terminus. Forms a nucleoprotein filament with DNA as an early intermediate in recombination (400 aa)

YEN1
Holliday junction resolvase; localization is cell-cycle dependent and regulated by Cdc28p phosphorylation; homolog of human GEN1 and has similarity to S. cerevisiae endonuclease Rth1p; Endonuclease which resolves Holliday junctions by the introduction of symmetrically related cuts across the junction point, to produce nicked duplex products in which the nicks can be readily ligated. Four-way DNA intermediates, also known as Holliday junctions, are formed during homologous recombination and DNA repair, and their resolution is necessary for proper chromosome segregation. Involved in DNA- [...] (759 aa)

RAD54
DNA-dependent ATPase, stimulates strand exchange by modifying the topology of double-stranded DNA; involved in the recombinational repair of double-strand breaks in DNA during vegetative growth and meiosis; member of the SWI/SNF family; Involved in DNA repair and mitotic recombination. Functions in the recombinational DNA repair (RAD52) pathway. Dissociates RAD51 from nucleoprotein filaments formed on dsDNA. Could be involved in the turnover of RAD51 protein-dsDNA filaments.
