Rad52
What is the Rad52 protein? The Saccharomyces cerevisiae Rad52 protein is a key player in DNA doublestrand break repair and homologous recombination. It forms a heptameric ring, catalyses DNA annealing and mediates Rad51-catalysed strand invasion. RAD52 is the defining member of an epistasis group of genes involved in repair of ionizing radiationinduced DNA double-strand breaks. Double-strand br...
متن کاملPlasmid recombination in a rad52 mutant of Saccharomyces cerevisiae.
Using plasmids capable of undergoing intramolecular recombination, we have compared the rates and the molecular outcomes of recombination events in a wild-type and a rad52 strain of Saccharomyces cerevisiae. The plasmids contain his3 heteroalleles oriented in either an inverted or a direct repeat. Inverted repeat plasmids recombine approximately 20-fold less frequently in the mutant than in the...
متن کاملEffects of the RAD52 Gene on Recombination in SACCHAROMYCES CEREVISIAE.
Effects of the rad52 mutation in Saccharomyces cerevisiae on meiotic, gamma-ray-induced, UV-induced and spontaneous mitotic recombination were studied. The rad52/rad52 diploids undergo premeiotic DNA synthesis; sporulation occurs but inviable spores are produced. Both intra and intergenic recombination during meiosis were examined in cells transferred from sporulation medium to vegetative mediu...
متن کاملPromotion of presynaptic filament assembly by the ensemble of S. cerevisiae Rad51 paralogues with Rad52
The conserved budding yeast Rad51 paralogues, including Rad55, Rad57, Csm2 and Psy3 are indispensable for homologous recombination (HR)-mediated chromosome damage repair. Rad55 and Rad57 are associated in a heterodimer, while Csm2 and Psy3 form the Shu complex with Shu1 and Shu2. Here we show that Rad55 bridges an interaction between Csm2 with Rad51 and Rad52 and, using a fully reconstituted sy...
متن کاملRad52 forms DNA repair and recombination centers during S phase.
Maintenance of genomic integrity and stable transmission of genetic information depend on a number of DNA repair processes. Failure to faithfully perform these processes can result in genetic alterations and subsequent development of cancer and other genetic diseases. In the eukaryote Saccharomyces cerevisiae, homologous recombination is the major pathway for repairing DNA double-strand breaks....
