STRINGSTRING
MMS4 protein (Saccharomyces cerevisiae) - STRING interaction network
"MMS4" - Subunit of the structure-specific Mms4p-Mus81p endonuclease that cleaves branched DNA 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

MMS4Subunit of the structure-specific Mms4p-Mus81p endonuclease that cleaves branched DNA; involved in recombination, DNA repair, and joint molecule formation/resolution during meiotic recombination; Interacts with MUS81 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 upstream of the free 5’-end in these structur [...] (691 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).

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)

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)

SRS2
DNA helicase and DNA-dependent ATPase involved in DNA repair, needed for proper timing of commitment to meiotic recombination and transition from Meiosis I to II; blocks trinucleotide repeat expansion; affects genome stability; ATP-dependent DNA helicase involved in DNA repair at least for UV-induced lesions. The polarity of the helicase activity was determined to be 3’ to 5’ (1174 aa)

RMI1
Subunit of the RecQ (Sgs1p) - Topo III (Top3p) complex; stimulates superhelical relaxing and ssDNA binding activities of Top3p; involved in response to DNA damage; null mutants display increased rates of recombination and delayed S phase; Structure-specific DNA-binding protein with a preference for cruciform structures. Also binds single-stranded DNA (ssDNA). Functions together with SGS1 and TOP3 to maintain genome integrity. Essential for proper meiotic cell division. Required for normal S-phase progression and DNA damage response. Required for resistance to the DNA-damaging agent met [...] (241 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)
