DNA-bound RAD52 is efficient at capturing ssDNA in trans.
Structure of the human DNA-repair protein RAD52 containing surface mutations has been reported.
Rad52 inverse strand exchange plays an important role in RNA-templated double strand break repair in vivo.
The mitotic DNA synthesis is RAD52 dependent, and RAD52 is required for the timely recruitment of MUS81 (show MUS81 Proteins) and POLD3 (show POLD3 Proteins) to common fragile sites in early mitosis.
Human RAD52-null cells retain a significant level of single-strand annealing (SSA (show TRIM21 Proteins)) activity demonstrating perforce that additional SSA (show TRIM21 Proteins)-like activities must exist in human cells. Moreover, the SSA (show TRIM21 Proteins) activity associated with RAD52 is involved in, but not absolutely required for, most homology-directed repair (HDR (show GATA3 Proteins)) subpathways. Specifically, a deficiency in RAD52 impaired the repair of DNA DSBs.
Data suggest RAD52 binds tightly to RPA (show RPA1 Proteins)/ssDNA complex in presynaptic complex and inhibits RPA (show RPA1 Proteins) turnover; during presynaptic complex assembly, most of RPA (show RPA1 Proteins) and RAD52 is displaced from ssDNA, but some RAD52/RPA (show RPA1 Proteins)/ssDNA complexes persist as interspersed clusters surrounded by RAD51 (show RAD51 Proteins) filaments. (RAD52 = Rad52 DNA repair/recombination protein (show RAD50 Proteins); RPA (show RPA1 Proteins) = replication protein A (show GPR153 Proteins); ssDNA = single-stranded DNA; RAD51 (show RAD51 Proteins) = Rad51 (show RAD51 Proteins) recombinase (show RAG1 Proteins))
The C-terminal region of yRad52, but not of hRAD52, is involved in ssDNA annealing. This suggests that the second DNA binding site is required for the efficient ssDNA annealing by yRad52. We propose an updated model of Rad52-mediated ssDNA annealing.
Study discovered two cis (show CISH Proteins)-expression quantitative trait loci SNPs in the RAD52 gene that are associated with its expression and are also associated with lung squamous cell carcinomas (LUSC) risk.
BRG1 (show SMARCA4 Proteins)-RAD52 complex mediates the replacement of RPA (show RPA1 Proteins) with RAD51 (show RAD51 Proteins) on single-stranded DNA (ssDNA) to initiate DNA strand invasion. Loss of BRG1 (show SMARCA4 Proteins) results in a failure of RAD51 (show RAD51 Proteins) loading onto ssDNA, abnormal homologous recombination repair
these results implicate increased RAD52 expression in both genetic susceptibility and tumorigenesis of upper aerodigestive tract and lung squamous cell carcinoma tumors.
In cancer-prone, heterozygous APC (show APC Proteins) mutant mice, homozygous deletion of the Rad52 gene suppressed tumor growth and prolonged lifespan.
Rad54 (show RAD54L Proteins) has a key function in maintaining genomic integrity of the developing germ cells.
Loss of Rad52 partially rescues tumorigenesis and T-cell maturation in Atm (show ATM Proteins)-deficient mice.
RAD52 modulates the outcome of recombinant HIV-l vector infection by markedly reducing the efficiency of productive integration events
Inactivation of RAD52 aggravates X-ray and mitomycine C sensitivity in mice with RAD54 (show RAD54L Proteins) gene degect.
Cells expressing Rad52 splice variants favor sister chromatid repair.
Results indicate that RAD52 cooperates with OGG1 (show OGG1 Proteins) to repair oxidative DNA damage and enhances the cellular resistance to oxidative stress.
The complete cDNA sequences of the pig RAD51 (show RAD51 Proteins), RAD52, and RAD54 (show RAD54L Proteins) genes, which are closely related to homologous recombination events, arae identified using molecular cloning technique in pigs.
Rad51 (show RAD51 Proteins) and Rad52 physically interact with CENP-ACaCse4 in vivo.
Rad52 prevents chromosome loss and truncation.
The protein encoded by this gene shares similarity with Saccharomyces cerevisiae Rad52, a protein important for DNA double-strand break repair and homologous recombination. This gene product was shown to bind single-stranded DNA ends, and mediate the DNA-DNA interaction necessary for the annealing of complementary DNA strands. It was also found to interact with DNA recombination protein RAD51, which suggested its role in RAD51 related DNA recombination and repair.
