RAD51 also known as recombination protein A or Novus RAD51 is a DNA repair protein with a molecular mass of approximately 37 kDa. This protein plays a significant role in homologous recombination and is active in the repair of double-strand breaks in DNA. It is expressed in various tissues with high levels seen in rapidly dividing cells. RAD51 acts by forming nucleoprotein filaments on single-stranded DNA and facilitates the search for homology and strand pairing during the repair process.
Biological function summary

Processes involving RAD51 are essential for genomic stability and cellular response to DNA damage. RAD51 often functions as part of a repair complex along with other proteins such as BRCA2 and RPA. This complex binds and stabilizes single-stranded DNA during search and strand invasion which is vital for successful recombination repair. Such repair mechanisms are important for preventing chromosomal aberrations and maintaining genetic integrity.

Pathways

RAD51's activity fits into the broader context of DNA damage repair pathways notably the homologous recombination (HR) pathway. This pathway is important for repairing double-strand breaks utilizing other proteins such as ATM and ATR to signal repair processes. Furthermore RAD51 interacts with various members of the BRCA protein family combining efforts to ensure proper DNA damage response and repair.

RAD51 mutations or dysregulation are linked to various types of cancer including breast and ovarian cancers. These cancers may involve mutations in BRCA1 and BRCA2 genes which affect RAD51's ability to effectively perform homologous recombination. Additionally disruptions in RAD51 function are associated with Fanconi anemia a disorder characterized by DNA repair defects. This condition demonstrates the importance of RAD51's interaction with FA pathway proteins in maintaining genomic stability and preventing disease.

General info

Function

The protein expressed by the RAD51 gene plays an important role in homologous strand exchange, a critical step in DNA repair through homologous recombination (HR). It binds to single and double-stranded DNA and exhibits DNA-dependent ATPase activity, catalyzing 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. RAD51 binds to single-stranded DNA in an ATP-dependent manner to form nucleoprotein filaments essential for the homology search and strand exchange. It is part of a PALB2-scaffolded HR complex containing BRCA2 and RAD51C, which is thought to play a role in DNA repair by HR. RAD51 also plays a role in regulating mitochondrial DNA copy number under conditions of oxidative stress in the presence of RAD51C and XRCC3 and is involved in interstrand cross-link repair.

Sequence similarities

Belongs to the RecA family. RAD51 subfamily.

Post-translational modifications

Ubiquitinated by the SCF(FBH1) E3 ubiquitin ligase complex, regulating RAD51 subcellular location and preventing its association with DNA. Ubiquitinated by RFWD3 in response to DNA damage: ubiquitination leads to degradation by the proteasome, promoting homologous recombination (PubMed:28575658).. Phosphorylation of Thr-309 by CHEK1 may enhance association with chromatin at sites of DNA damage and promote DNA repair by homologous recombination (PubMed:15665856). Phosphorylated at Ser-14 by PLK1, triggering phosphorylation at Thr-13 by CK2, thereby promoting interaction with TOPBP1 and recruitment to DNA damage sites during S-phase (PubMed:22325354, PubMed:26811421). Phosphorylation by ABL1 inhibits function (PubMed:9461559).
