SRS2 protein (Saccharomyces cerevisiae) - STRING interaction network
"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 in Saccharomyces cerevisiae
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 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
protein homology

SRS2DNA 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)    
Predicted Functional Partners:
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)
Proliferating cell nuclear antigen (PCNA), functions as the sliding clamp for DNA polymerase delta; may function as a docking site for other proteins required for mitotic and meiotic chromosomal DNA replication and for DNA repair; This protein is an auxiliary protein of DNA polymerase delta and is involved in the control of eukaryotic DNA replication by increasing the polymerase’s processibility during elongation of the leading strand. Involved in DNA repair (258 aa)
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)
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. Addition of RAD54 overcomes inhibition of DNA strand exchange by RAD51 bound to substrate dsDNA. Species prefere [...] (898 aa)
Protein that stimulates strand exchange by stabilizing the binding of Rad51p to single-stranded DNA; involved in the recombinational repair of double-strand breaks in DNA during vegetative growth and meiosis; forms heterodimer with Rad55p; Participates in the repair of X-ray-induced damage to DNA and in meiosis. It may act in part by stabilizing a repair complex of other RAD genes (460 aa)
Ubiquitin-conjugating enzyme (E2), involved in postreplication repair (as a heterodimer with Rad18p), DSBR and checkpoint control (as a heterodimer with Bre1p), ubiquitin-mediated N-end rule protein degradation (as a heterodimer with Ubr1p; Catalyzes the covalent attachment of ubiquitin to other proteins. In association with the E3 enzyme BRE1 and LGE1, it plays a role in transcription regulation by catalyzing the monoubiquitination of histone H2B to form H2BK123ub1. H2BK123ub1 gives a specific tag for epigenetic transcriptional activation, elongation by RNA polymerase II, telomeric si [...] (172 aa)
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)
DNA helicase proposed to promote replication fork regression during postreplication repair by template switching; RING finger containing ubiquitin ligase; stimulates the synthesis of free and PCNA-bound polyubiquitin chains by Ubc13p-Mms2p; Probable helicase, member of the UBC2/RAD6 epistasis group. Functions with the DNA repair protein RAD18 in error-free postreplication DNA repair. Involved in the maintenance of wild- type rates of instability of simple repetitive sequences such as poly(GT) repeats. Seems to be involved in maintaining a balance which acts in favor of error-prone non- [...] (1169 aa)
Protein that stimulates strand exchange by facilitating Rad51p binding to single-stranded DNA; anneals complementary single-stranded DNA; involved in the repair of double-strand breaks in DNA during vegetative growth and meiosis; Involved in DNA double-strand break (DSB) repair and recombination. Promotes the annealing of complementary single- stranded DNA and by stimulation of the RAD51 recombinase (471 aa)
E3 ubiqutin ligase, forms heterodimer with Rad6p to monoubiquitinate PCNA-K164; heterodimer binds single-stranded DNA and has single-stranded DNA dependent ATPase activity; required for postreplication repair; E3 RING-finger protein, member of the UBC2/RAD6 epistasis group. Associates to the E2 ubiquitin conjugating enzyme UBC2/RAD6 to form the UBC2-RAD18 ubiquitin ligase complex involved in postreplicative repair (PRR) of damaged DNA. The UBC2-RAD18 complex cooperates with RAD5 and the UBC13-MMS2 dimer to attach mono-ubiquitin chains on ’Lys-164’ of POL30, which is necessary for PRR. [...] (487 aa)
