FunctionPlays an important role in homologous strand exchange, a key step in DNA repair through homologous recombination. Binds to single and double-stranded DNA and exhibits DNA-dependent ATPase activity. Catalyzes the recognition of homology and strand exchange between homologous DNA partners to form a joint molecule between a processed DNA break and the repair template. Binds to single-stranded DNA in an ATP-dependent manner to form nucleoprotein filaments which are essential for the homology search and strand exchange (PubMed:26681308). Part of a PALB2-scaffolded HR complex containing BRCA2 and RAD51C and which is thought to play a role in DNA repair by HR. Plays a role in regulating mitochondrial DNA copy number under conditions of oxidative stress in the presence of RAD51C and XRCC3.
Tissue specificityHighly expressed in testis and thymus, followed by small intestine, placenta, colon, pancreas and ovary. Weakly expressed in breast.
Involvement in diseaseBreast cancer
Mirror movements 2
Defects in RAD51 are found in a patient with microcephaly, mental retardation without bone marrow failure and pediatric cancers.
Sequence similaritiesBelongs to the RecA family. RAD51 subfamily.
Contains 1 HhH domain.
DomainThe nuclear localization may reside in the C-terminus (between 259 and 339 AA).
modificationsUbiquitinated by the SCF(FBXO18) E3 ubiquitin ligase complex, regulating RAD51 subcellular location and preventing its association with DNA.
Phosphorylated. Phosphorylation of Thr-309 by CHEK1 may enhance association with chromatin at sites of DNA damage and promote DNA repair by homologous recombination. Phosphorylation by ABL1 inhibits function.
Cellular localizationNucleus. Cytoplasm. Cytoplasm, perinuclear region. Mitochondrion matrix. Cytoplasm, cytoskeleton, microtubule organizing center, centrosome. Colocalizes with RAD51AP1 and RPA2 to multiple nuclear foci upon induction of DNA damage. DNA damage induces an increase in nuclear levels. Together with FIGNL1, redistributed in discrete nuclear DNA damage-induced foci after ionizing radiation (IR) or camptothecin (CPT) treatment. Accumulated at sites of DNA damage in a SPIDR-dependent manner.

Goat anti-Rabbit IgG conjugated to HRP at 1/20000 dilution
Predicted band size: 36 kDa
ab176458 (20 µg) was incubated with 20 μg of HeLa cell extract, and precipitated with 20 μg of proteinA-beads. The sample was dissociated from the precipitate by heating in SDS-sample buffer and analyzed by western blotting with anti-Rad51 antiserum (chicken, ab63802) at 1/1000 dilution. As secondary antibody, anti-chicken IgG antibody (rabbit) was used at 1/10000 dilution.
Immunohistological staining of Rad51 protein in mouse testis using ab176458. A section of formalin fixed and paraffin embedded mouse testis was treated with ab176458 at 1/100 dilution after deparaffization and antigen retrieval. The secondary antibody, Alexa Fluor® 647conjugated anti-rabbit IgG was used at 1/1,000 dilution (top left). The sample was counter-stained with DAPI (top right) and the merged image is shown (bottom left). The white light image of the same region is shown on the bottom right.
