We demonstrate an almost mutually exclusive subcompartmentalization with Rad 52 , while p53pSer15 was colocalizing with 40 60 % of the Rad 51 and Mre 11 foci . ^^^ Therefore , possible sites of p53pSer15 dependent regulation seem to be sites of Rad 51 rather than Rad 52 dependent HR processes . ^^^

Ionizing radiation induced foci formation of mammalian Rad 51 and Rad 54 depends on the Rad 51 paralogs , but not on Rad 52 . ^^^ Biochemical experiments have revealed that during the process of homologous recombination the RAD 52 group proteins , including Rad 51 , Rad 52 and Rad 54 , are involved in an essential step : formation of a joint molecule between the broken DNA and the intact repair template . ^^^ The significance of homologous recombination for the cell is underscored by the evolutionary conservation of the Rad 51 , Rad 52 and Rad 54 proteins from yeast to humans . ^^^ For the yeast Saccharomyces cerevisiae , foci formation of Rad 51 and Rad 54 is abrogated in the absence of Rad 52 , while Rad 51 foci formation does occur in the absence of the Rad 51 paralog Rad 55 . ^^^ By contrast , we show here that in mammalian cells , Rad 52 is not required for foci formation of Rad 51 and Rad 54 . ^^^

Using co immunoprecipitation assays , we showed that cellular interaction of RPA with two DSB repair factors , Rad 51 and Rad 52 , was predominantly mediated by the hyperphosphorylated species of RPA in cells after UV and camptothecin treatment . ^^^ Moreover , Rad 51 and Rad 52 displayed higher affinity for the hyperphosphorylated RPA than native RPA in an in vitro binding assay . ^^^
