Gene Description

RAD51 is the central eukaryotic recombinase of homologous recombination (HR), the ortholog of bacterial RecA and yeast Rad51. It binds single-stranded DNA in an ATP-dependent manner to assemble a helical nucleoprotein (presynaptic) filament on the 3' single-stranded overhangs generated by end resection, after being loaded onto RPA-coated ssDNA by BRCA2/PALB2 and the RAD51 paralog mediators (the BCDX2 and CX3 complexes; RAD51B, RAD51C, RAD51D, XRCC2, XRCC3). The active ATP-bound filament performs homology search within duplex DNA and catalyzes DNA strand invasion and strand exchange, base-pairing the invading strand with the homologous template to form a displacement loop (D-loop). RAD51 is a self-inactivating, DNA-dependent ATPase: ATP binding and hydrolysis, modulated by cofactors such as Ca2+, control filament assembly, stability and turnover. Through this recombinase activity RAD51 is essential for error-free repair of DNA double-strand breaks by HR, for protection and restart of stalled or damaged replication forks, and for interstrand crosslink repair; it also acts at chromatin and can peel nucleosomal DNA at break sites. Additional context- specific roles include meiotic recombination (as a non-catalytic accessory to the meiosis-specific recombinase DMC1), recombination-based telomere maintenance, and maintenance of mitochondrial DNA copy number under oxidative stress. RAD51 is nuclear and concentrates in damage-induced foci at sites of double-strand breaks. A dominant- negative RAD51 variant causes a Fanconi anemia-like disorder (Fanconi anemia complementation group R, FANCR).

Core Functions

Assembles into an ATP-dependent nucleoprotein (presynaptic) filament on single-stranded DNA and catalyzes homology search, DNA strand invasion and strand exchange to form a D-loop โ€” the core recombinase activity that repairs double-strand breaks by homologous recombination, protects/restarts stalled replication forks, and contributes to interstrand crosslink repair.

  • PMID:8929543
    hRad51 promotes homologous pairing and strand exchange reactions in vitro.
  • PMID:27694622
    displacing the homologous strand to form a displacement loop (D-loop)
  • PMID:9012806
    The recombinant human protein carries out the hallmark reactions of RecA protein, including DNA-dependent hydrolysis of ATP, renaturation of complementary strands, homologous pairing of a single strand with duplex DNA, and strand exchange.

Binds single-stranded DNA to nucleate assembly of the RAD51 recombinase filament, the first committed step of the presynaptic filament that carries out homology search and strand exchange.

Supporting Evidence:
  • PMID:7988572
    The human Rad51 protein binds to single- and double-stranded DNA and exhibits DNA-dependent ATPase activity.

Binds and hydrolyzes ATP as a self-inactivating DNA-dependent ATPase; the nucleotide state governs assembly, stability and turnover of the nucleoprotein filament and thereby regulates strand-exchange activity.

Supporting Evidence:
  • PMID:15226506
    due to relatively rapid ATP hydrolysis and slow dissociation of ADP
  • PMID:9012806
    the low rate of hydrolysis of ATP affects a rate-limiting step that is essential for both homologous pairing and strand exchange

Suggested Questions for Experts

Q: To what extent are RAD51's mitochondrial mtDNA-maintenance and nuclear HR functions mechanistically separable, and does mitochondrial RAD51 act as a recombinase there?

Q: How is the balance between RAD51 filament stabilization (BRCA2, RAD51AP1) and active dismantling (FIGNL1, RECQL5, PARI/PARPBP) controlled to switch between HR and fork protection outcomes?

Suggested Experiments

Experiment: Separation-of-function RAD51 mutants (e.g. FANCR-type dominant variants) assayed in parallel for HR, replication fork protection, and ICL repair to map the domains/activities specific to each process.

Experiment: Single-molecule / cryo-EM analysis of RAD51 filament dynamics on nucleosomal versus naked DNA to quantify the nucleosome-peeling step and its ATP dependence.

Current model (mechanistic narrative)

RAD51 is the central eukaryotic recombinase that assembles as an ATP-dependent nucleoprotein filament on single-stranded DNA and catalyzes homology search and DNA strand exchange, the core reaction of homologous recombination PMID:9012806. Filament assembly on RPA-coated ssDNA is rate-limited by nucleation, which BRCA2 overcomes by chaperoning a preassembled RAD51 nucleus onto ssDNA, displacing RPA and stabilizing the filament against ATP hydrolysis [PMID:20729832, PMID:36976771]; a C-terminal BRCA2 TR2 motif braces adjacent protomers across the filament interface, while the BRC repeats engage distinct RAD51 surfaces [PMID:37919288, PMID:15937124]. The filament's recombinase activity is intrinsically coupled to ATP hydrolysis and to an inter-subunit ATP cap that tunes turnover versus strand-exchange efficiency [PMID:9012806, PMID:22275364], and Loop2 residues impose strict mismatch intolerance that distinguishes RAD51 from its meiotic counterpart DMC1 PMID:34871438. A broad network of mediators governs the filament: RAD52 targets RAD51 to RPA-ssDNA and channels lesions between strand invasion and annealing [PMID:9450760, PMID:9450758, PMID:18337252], Rad54 stimulates homologous pairing and branch migration and drives ATPase-dependent filament turnover from duplex DNA [PMID:9590697, PMID:17567608, PMID:18617519], the RAD51 paralogs assemble into complexes that remodel and stabilize presynaptic filaments [PMID:10749867, PMID:26186187, PMID:23810717], and HOP2-MND1 and FANCD2/FANCI further stimulate or stabilize the filament [PMID:24943459, PMID:27694619, PMID:37526271]. Filament abundance at replication forks is set antagonistically by RADX, which competes for ssDNA, stimulates RAD51 ATPase, and destabilizes filaments in opposition to BRCA2 [PMID:30021152, PMID:33453169, PMID:32621611]. Chromatin loading is controlled by post-translational modification, including TOPBP1/PLK1-dependent Ser14 phosphorylation, Mec1-dependent phosphorylation of the yeast enzyme, and TOPORS-dependent SUMOylation [PMID:26811421, PMID:21738226, PMID:35061896]. Beyond canonical double-strand break repair and break-induced replication PMID:14993274, RAD51 protects stalled and nascent replication forksโ€”catalyzing fork reversal while bypassing the bound CMG helicase, shielding abasic sites and nascent strands from MRE11/DNA2/EXO1 nucleases, and suppressing transcription-replication conflicts [PMID:37104614, PMID:39178838, PMID:37526271, PMID:36002000]; in its absence, MRE11-driven degradation of unprotected nascent DNA releases cytosolic fragments that activate STING-mediated innate immunity PMID:28334891. RAD51 also promotes mitotic DNA synthesis and centromere integrity [PMID:34508092, PMID:36702125] and forms TERRA R-loops at telomeres PMID:33057192.

Dated findings (citation-anchored)

Year Confidence Finding PMIDs Journal
2010 High Purified full-length human BRCA2 promotes assembly of RAD51 onto single-stranded DNA (ssDNA) by targeting RAD51 to ssDNA over double-stranded DNA, enabling RAD51 to displace RPA from ssDNA, and stabilizing RAD51-ssDNA filaments by blocking ATP hydrolysis. BRCA2 does not mediate ssDNA annealing. PMID:20729832 Nature
1998 High Yeast Rad52 protein stimulates DNA strand exchange by Rad51 by targeting Rad51 to RPA-coated ssDNA, overcoming the inhibitory effect of RPA on presynaptic filament formation; stimulation requires concerted action of Rad51, Rad52, and RPA via specific protein-protein interactions. PMID:9450760, PMID:9450758 Nature
1998 High Yeast Rad54 protein physically interacts with Rad51 and strongly stimulates the rate of homologous DNA pairing between ssDNA and dsDNA catalyzed by Rad51; Rad54 possesses a dsDNA-dependent ATPase activity. PMID:9590697 Nature
1997 High Purified human RAD51 (HsRad51) catalyzes ATP-dependent homologous pairing and DNA strand exchange in vitro; rates of ATP hydrolysis, homologous pairing, and strand exchange by HsRad51 are less than 1/10 those of RecA. In the presence of ATP-ฮณS, HsRad51 forms stable presynaptic complexes and promotes renaturation but does not catalyze strand exchange or homologous pairing with duplex DNA, suggesting that homologous pairing and strand exchange by HsRad51 are more closely linked to ATP hydrolysis than in RecA. PMID:9012806 Proceedings of the National Academy of Sciences of the United States of America
1998 High Human Rad52 stimulates homologous pairing by human Rad51; hRad52 binds ssDNA and is involved in an early stage of Rad51-mediated recombination. PMID:9450758 Nature
2005 High BRCA2 BRC repeats (BRC3 and BRC4) bind RAD51-DNA nucleoprotein filaments at lower molar ratios and only disrupt filaments at high concentrations. BRC3 contacts the N-terminal domain of RAD51 and BRC4 contacts the nucleotide-binding core, showing that BRC repeats are non-equivalent in their mode of interaction with RAD51 filaments. PMID:15937124 Proceedings of the National Academy of Sciences of the United States of America
2000 Medium Human Rad51 redistributes to selectively UV-damaged, halogenated-thymidine-labeled chromatin after UV microirradiation, with recruitment occurring from pre-existing S-phase nuclear foci. Rad51 foci associate preferentially with postreplicative rather than replicating chromatin, supporting a role in recombinational repair of damage in postreplicative chromatin. PMID:10908572 The Journal of cell biology
2004 Medium RAD51 is required for more than 95% of break-induced replication (BIR) events at unique chromosomal sequences in yeast, demonstrating a genetic requirement for RAD51 in strand invasion during BIR. PMID:14993274 Molecular and cellular biology
2000 Medium Human RAD51 paralogs (XRCC2, XRCC3, RAD51B, RAD51C, RAD51D) form simultaneous protein interactions with each other and with HsRAD51; three-hybrid and baculovirus co-purification experiments show that some interactions (e.g., RAD51B-RAD51D) require a third paralog (RAD51C) to occur, suggesting they may form multi-protein complexes. PMID:10749867 The Journal of biological chemistry
1999 Medium The C-terminal region of HsRad51 contains amino acid residues required for binding to HsRad52; mutations in this region (not the N-terminal domain) impair HsRad52 binding. The HsRad51 F259V mutation, which abrogates HsRad52 binding, reduces the stimulation of homologous pairing that occurs with both proteins together without affecting HsRad51-only pairing, establishing that the HsRad51-HsRad52 interaction is important for cooperative homologous pairing. PMID:10448035 Journal of molecular biology
2007 Medium Efficient turnover of Rad51 from dsDNA after strand exchange requires both the Rad51 ATPase activity and the Rad54 ATPase activity; the catalytic efficiency of Rad54's ATPase is stimulated by Rad51 partial filaments on dsDNA. The Rad51-K191R ATPase-dead mutant forms filaments with significantly increased stability on DNA. PMID:17567608 Nucleic acids research
2008 High Rad51 inhibits Rad52-mediated annealing of complementary ssDNA in an ATP-dependent manner through specific protein-protein interaction; the Rad51 nucleoprotein filament is more inhibitory than free Rad51. Rad59 partially restores Rad52 annealing in the presence of Rad51, suggesting coordinated channeling of processed DSBs to either strand invasion or annealing pathways. PMID:18337252 The Journal of biological chemistry
2008 Medium Human Rad51 specifically stimulates the branch migration activity of human Rad54 through protein-protein interactions; the active conformation of the hRad51 filament is more stimulatory than the inactive form. This stimulation is evolutionarily conserved (also observed with yeast proteins). PMID:18617519 The Journal of biological chemistry
2009 Medium Human PSF directly interacts with RAD51 through its N-terminal region and modulates RAD51-mediated homologous pairing and strand exchange in a concentration-dependent biphasic manner: stimulating at low RAD51 concentrations and inhibiting at optimal RAD51 concentrations. PMID:19447914 Nucleic acids research
2015 High The C. elegans RAD51 paralog complex RFS-1/RIP-1 binds pre-synaptic RAD51 filaments and remodels them to a stabilized, 'open,' and flexible conformation in which ssDNA is more accessible and RAD51 dissociation rate is reduced. Walker box mutations in RFS-1 that abolish filament remodeling also abolish stimulation of RAD51 strand exchange, demonstrating that remodeling activity is essential for function. PMID:26186187 Cell
2016 Medium TOPBP1 promotes PLK1 kinase-mediated phosphorylation of RAD51 at serine 14, which is required for RAD51 recruitment to chromatin (chromatin loading and foci formation) during homologous recombination repair; TOPBP1 BRCT domains 7/8 are essential for RAD51 foci formation. PMID:26811421 The Journal of cell biology
2018 Medium RADX antagonizes RAD51 by competing with RAD51 for binding to ssDNA, modulating the amount of RAD51 at stalled replication forks. Loss of RADX restores fork protection in BRCA1-, BRCA2-, FANCA-, FANCD2-, or BOD1L-deficient cells; overexpression of RADX causes fork degradation dependent on MRE11 and DNA2 nucleases and fork reversal. PMID:30021152 Cell reports
2021 High RADX directly and selectively interacts with ATP-bound RAD51, stimulates RAD51 ATP hydrolysis, and destabilizes RAD51 nucleofilaments, thereby inhibiting RAD51 strand exchange and D-loop formation. BRCA2 can overcome RADX-dependent RAD51 inhibition, placing RADX in functional opposition to BRCA2 in regulating RAD51 nucleofilament stability during DNA replication. PMID:33453169 Molecular cell
2020 High RADX condenses ssDNA filaments (including RPA-coated ssDNA) via higher-order assemblies, blocks RPA displacement by RAD51, and prevents RAD51 loading onto ssDNA, functioning as a negative regulator of RAD51 filament formation. PMID:32621611 Nucleic acids research
2023 Medium RAD51 uses its strand exchange activity to bypass the CMG replicative helicase (which remains bound to a stalled fork) during replication fork reversal. If the helicase is unloaded, RAD51 is no longer required for fork reversal. Thus RAD51 creates a parental DNA duplex behind the helicase that DNA translocases use for branch migration to generate the reversed fork structure. PMID:37104614 Science (New York, N.Y.)
2017 Medium RAD51 deficiency leads to accumulation of self-DNA in the cytoplasm, triggering a STING-mediated innate immune response; the unprotected nascent genome in RAD51-deficient cells is degraded by MRE11 exonuclease, and the resulting fragmented nascent DNA accumulates in the cytosol to initiate innate immune signaling. PMID:28334891 Nucleic acids research
2016 Medium FANCI-FANCD2 (I-D) complex directly binds RAD51 and stabilizes the RAD51-DNA filament in a manner requiring the DNA-binding activity of FANCI; the stabilized filament protects the 5'-DNA end from FAN1 nucleolytic degradation. The RAD51 mutant from FANCR patient cells fails to achieve this protection. PMID:27694619 Nucleic acids research
2014 High HOP2-MND1 heterodimer stimulates RAD51 DNA strand exchange by inducing conformational changes in RAD51 that enhance interaction with nucleotide cofactors, modify DNA-binding specificity, facilitate RAD51 loading onto ssDNA, and promote dsDNA binding during the homology search; HOP2-MND1 enables strand exchange in the absence of divalent metal ions and offsets the K133A ATP-binding mutation. PMID:24943459 Nature communications
2012 High The conserved aspartate at the inter-subunit ATP cap (Asp-316 in human RAD51) forms a salt bridge with the ATP ฮณ-phosphate in the nucleoprotein filament, enhancing filament turnover at the expense of recombinase activity; substitution of Asp-316 with lysine (HsRAD51-D316K) decreases NPF turnover and markedly improves strand exchange activity in the absence of salt. PMID:22275364 The Journal of biological chemistry
2011 Medium Yeast Rad51 is phosphorylated on Ser192 in a DNA-damage-responsive manner primarily mediated by the Mec1 kinase; Ser192 Ala and Glu mutations confer hypersensitivity to DNA damage and homologous recombination defects. Ser192 is required for Rad51 ATPase activity and DNA-binding activity in vitro but not for multimer formation. PMID:21738226 EMBO reports
2013 Medium The HsRAD51B-HsRAD51C heterodimer forms a stable complex on ssDNA and partially stabilizes HsRAD51 nucleoprotein filaments against BLM helicase anti-recombinogenic activity; HsRAD51B-HsRAD51C also stimulates HsRAD51-mediated D-loop formation in the presence of RPA but does not facilitate RAD51 nucleation on RPA-coated ssDNA. PMID:23810717 DNA repair
2022 Medium TOPORS acts as a SUMO E3 ligase that SUMOylates RAD51 at lysine residues 57 and 70 in response to DNA damage; TOPORS SUMOylation is facilitated by ATM-induced phosphorylation of TOPORS at Thr515. SUMOylation of RAD51 is required for its chromatin recruitment and homologous recombination repair; SUMOylation-deficient RAD51 has reduced association with BRCA2. PMID:35061896 Nucleic acids research
2021 Medium RAD51 protects under-replicated DNA in mitotic cells and promotes mitotic DNA synthesis (MiDAS) and successful chromosome segregation; MiDAS requires de novo RAD51 recruitment to ssDNA supported by Polo-like kinase 1 (PLK1)-mediated phosphorylation of RAD51. Acute inhibition of MiDAS delays anaphase onset and induces centromere fragility. PMID:34508092 Nature communications
2023 High BRCA2's C-terminal TR2 motif binds across the protomer interface in the RAD51 nucleoprotein filament, acting as a brace for adjacent RAD51 molecules by targeting an acidic-patch motif on RAD51; structure-guided mutagenesis validated the functional importance of this interaction for filament stabilization. PMID:37919288 Nature communications
2023 High BRCA2 accelerates nucleation of RAD51 onto RPA-coated ssDNA to a rate approaching RAD51 association with naked ssDNA, eliminating the rate-limiting nucleation step by chaperoning a short preassembled RAD51 filament onto the ssDNA; a RAD51 dimer is the minimal unit required for spontaneous nucleation but growth self-terminates below the diffraction limit in the absence of BRCA2. PMID:36976771 Proceedings of the National Academy of Sciences of the United States of America
2024 High RAD51 nucleofilaments specifically recognize and protect abasic sites in ssDNA; abasic sites increase the RAD51 association rate to DNA. In the absence of BRCA2 or RAD51, abasic sites accumulate and induce abasic ssDNA gaps that make replicating DNA fibers sensitive to APE1. RAD51 assembled on abasic DNA prevents cleavage by the MRE11-RAD50 complex, suppressing replication fork breakage. PMID:39178838 Molecular cell
2021 Medium RAD51 physically interacts with TERRA lncRNA and catalyzes R-loop formation with TERRA in vitro, directly promoting TERRA recruitment to telomeres by strand invasion in trans; this process is counteracted by RNaseH1 and TRF1. PMID:33057192 Nature
2021 Medium RAD51 helicase HELQ is strongly stimulated by RAD51 during DNA unwinding via direct complex formation; conversely, RPA inhibits HELQ DNA unwinding but stimulates its DNA strand annealing activity. PMID:34937945 Nature
2021 Medium FANCD2, independent of FANCI dimerization, stabilizes RAD51 filaments to inhibit DNA2, MRE11, and EXO1 nucleases at stalled replication forks; additionally, FANCD2 acts as a RAD51 mediator to stimulate RAD51 strand exchange activity, providing a mechanistic link between FANCD2 and BRCA2 in the FA/BRCA fork protection pathway. PMID:37526271 Nucleic acids research
1998 Medium HsRad51 is proteolytically cleaved during apoptosis in human T-lymphocyte cell lines with similar kinetics to PARP cleavage; cleavage is blocked by the caspase inhibitor Ac-DEVD-CHO, implicating a DEVD-specific caspase, though purified caspases 2, 3, or 6-10 could not individually cleave HsRad51 in vitro. PMID:9607320 FEBS letters
2001 Medium Depletion of HsRad51 from human cell-free extracts diminishes triplex-induced recombination, and supplementation with purified HsRad51 restores it, establishing that HsRad51 is required for triplex-induced intermolecular recombination in human cell extracts. PMID:11278954 The Journal of biological chemistry
2022 Medium RAD51 Cys319 is a functionally significant redox-regulated site; oxidation of Cys319 disrupts DNA binding (molecular dynamics simulations show DNA dissociation from oxidized Cys319 RAD51 filament). Peroxiredoxin 1 (PRDX1) maintains Cys319 in a reduced state, and loss of PRDX1 leads to increased sulfenylation of RAD51 Cys319, impaired RAD51 foci formation, and decreased homologous recombination. PMID:36058112 Redox biology
2023 Medium Centromeric DNA breaks in quiescent human cells are resolved enzymatically by RAD51 recombinase, which safeguards the specification of functional centromeres. PMID:36702125 Molecular cell
2021 Medium RAD51 protects replication forks from transcription-replication conflicts (TRCs); RAD51-deficient regions enriched for early-S-phase replication and transcription show increased fork breakage, and inhibiting early S-phase transcription ameliorates many adverse effects of RAD51 depletion. PMID:36002000 Molecular cell
2021 High Cryo-EM structures of human RAD51-DNA complexes reveal that Loop2 residues V273 and D274 in RAD51 (vs. P274 and G275 in DMC1) are key determinants of mismatch intolerance during strand exchange; these differences in Loop2 that contact both ssDNA and the complementary strand explain why RAD51 does not permit HR in the presence of mismatches whereas DMC1 does. PMID:34871438 Nucleic acids research
2023 High In vivo, Rad51-ssDNA nucleoprotein filaments in budding yeast span the entire nucleus following DSB induction, adopting diverse shapes not seen in vitro; the filaments undergo cycles of compaction and extension modulated by Rad54 (promotes extension) and Srs2 (promotes compaction), and this compaction-extension dynamic constitutes a robust nuclear homology search strategy. PMID:37605042 Nature structural & molecular biology
2020 Medium Rad51 facilitates Dmc1 nucleoprotein filament assembly during meiosis through direct physical interaction; Dmc1 nucleation is stimulated by short Rad51 patches on DNA, and pull-down assays confirm a physical interaction between ScDmc1 and ScRad51 but not between ScDmc1 and EcRecA. PMID:32404423 Proceedings of the National Academy of Sciences of the United States of America
2018 Medium Rad51 and Dmc1 have an intrinsic ability to self-segregate within mixed presynaptic filaments in vitro, without any accessory proteins; Dmc1 stabilizes adjacent Rad51 filament segments, suggesting cross-talk between the two recombinases. PMID:29382724 The Journal of biological chemistry
2017 Medium Human RAD52 binds tightly to RPA-ssDNA and imposes an inhibitory effect on RPA turnover; during RAD51 presynaptic complex assembly, most RPA and RAD52 are displaced but some RAD52-RPA-ssDNA clusters persist interspersed within RAD51 filaments; once RAD51 filament assembles, it restricts new RAD52 binding events but RAD52 re-binds after RAD51 dissociation. PMID:28551686 The Journal of biological chemistry
1998 Medium BRCA2 gene product forms in vivo complexes with both RAD51 and p53 in human cells; BRCA2 is a nuclear phosphoprotein, and exogenous BRCA2 expression inhibits p53's transcriptional activity with RAD51 coexpression enhancing this inhibitory effect. PMID:9811893 Proceedings of the National Academy of Sciences of the United States of America

RAD51 (Q06609) gene review notes

Human RAD51 = DNA repair protein RAD51 homolog 1; RAD51 homolog A; FANCR
(Fanconi anemia complementation group R). The eukaryotic ortholog of E. coli
RecA and yeast Rad51 โ€” the central recombinase of homologous recombination (HR).

Core biology (established)

  • Recombinase / DNA strand exchange (core MF). RAD51 binds ssDNA in an
    ATP-dependent manner to form a helical nucleoprotein (presynaptic) filament,
    searches for homology in duplex DNA, and catalyzes strand invasion/exchange to
    form a D-loop. PMID:7988572; PMID:8929543;
    PMID:27694622; PMID:27694622.
  • ATP binding/hydrolysis regulates filament dynamics. RAD51 is a self-inactivating
    ATPase; the ATP-bound filament is active, ATP hydrolysis (and slow ADP release)
    inactivates it; Ca2+ preserves the active filament by slowing hydrolysis, stimulating
    strand exchange. PMID:15226506; PMID:15226506; PMID:15226506.
  • DSB repair via HR (core BP). Essential effector of HR-mediated double-strand
    break repair; loaded onto RPA-coated 3' ssDNA by BRCA2/PALB2 and the RAD51 paralog
    mediators (BCDX2, RAD51B/C/D, XRCC2/3). UniProt FUNCTION; many IDA annotations
    (PMID:12442171, 18417535, 19303847, 27941124, 37499663, 38509361, etc.).
  • Replication fork protection/restart (core BP). Recruited to stalled forks under
    replication stress; protects nascent DNA and enables fork restart. PMID:18417535;
    PMID:22778135;
    PMID:25585578 (FBH1/RAD51 ubiquitylation & fork stability).
  • Interstrand crosslink repair. RAD51 has a role in ICL repair; a dominant RAD51
    variant separates ICL repair from HR. PMID:26253028.
  • Nucleosome interaction. Cryo-EM: RAD51 filament binds nucleosomal DNA and peels
    it from the histone octamer. PMID:38509361;
    filament peels nucleosomal DNA (GO:0031491 nucleosome binding IDA).

Non-core / context-specific

  • Meiotic HR (accessory). By similarity RAD51 acts as a non-catalytic accessory
    factor for the meiosis-specific recombinase DMC1 (chromosome pairing/crossover);
    meiotic terms (GO:0007131, GO:0070192, GO:1990918, GO:0007127, GO:0000800 lateral
    element, GO:0051321, GO:0000793/0000794 condensed chromosome) are kept as NON_CORE
    in the human somatic context.
  • Mitochondrial mtDNA maintenance (separable). With RAD51C/XRCC3, regulates mtDNA
    copy number under oxidative stress. PMID:20413593; mitochondrion/mitochondrial matrix localization (GO:0005739,
    GO:0005759) kept NON_CORE.
  • Telomere maintenance via recombination (ALT context). GO:0000722/0010833/0000781
    kept NON_CORE (ortholog ISS/IEA).
  • Minor localizations kept NON_CORE: centrosome (GO:0005813), PML body (GO:0016605,
    PMID:11309417), nucleolus (GO:0005730 HPA), cytosol/cytoplasm/perinuclear
    (GO:0005829/0005737/0048471).

description: 'RAD51 is the central eukaryotic recombinase of homologous recombination (HR), the ortholog of bacterial RecA and yeast Rad51. It binds single-stranded DNA in an ATP-dependent manner to assemble a helical nucleoprotein (presynaptic) filament on the 3'' single-stranded overhangs generated by end resection, after being loaded onto RPA-coated ssDNA by BRCA2/PALB2 and the RAD51 paralog mediators (the BCDX2 and CX3 complexes; RAD51B, RAD51C, RAD51D, XRCC2, XRCC3). The active ATP-bound filament performs homology search within duplex DNA and catalyzes DNA strand invasion and strand exchange, base-pairing the invading strand with the homologous template to form a displacement loop (D-loop). RAD51 is a self-inactivating, DNA-dependent ATPase: ATP binding and hydrolysis, modulated by cofactors such as Ca2+, control filament assembly, stability and turnover. Through this recombinase activity RAD51 is essential for error-free repair of DNA double-strand breaks by HR, for protection and restart of stalled or damaged replication forks, and for interstrand crosslink repair; it also acts at chromatin and can peel nucleosomal DNA at break sites. Additional context- specific roles include meiotic recombination (as a non-catalytic accessory to the meiosis-specific recombinase DMC1), recombination-based telomere maintenance, and maintenance of mitochondrial DNA copy number under oxidative stress. RAD51 is nuclear and concentrates in damage-induced foci at sites of double-strand breaks. A dominant- negative RAD51 variant causes a Fanconi anemia-like disorder (Fanconi anemia complementation group R, FANCR).'
