Assembly of the RAD51-ssDNA nucleoprotein complex (R-HSA-76000)

Species Homo sapiens


The RAD51-ssDNA nucleoprotein filament is a right-hand helical nucleoprotein filament referred to as the presynaptic filament. This nucleoprotein complex contains a binding site for the double-stranded homologous DNA molecule with which it interacts during strand exchange. Loading of RAD51 onto ssDNA is thought to be facilitated by recombination mediator RAD52 (McIlwraith et al., 2000), RAD51 paralogs: RAD51B, RAD51C, RAD51D, XRCC2 and XRCC3 (Sigurdsson et al., 2001), by the association of RAD52 with ssDNA (Parsons et al., 2000) and by the association of RAD51 with BRCA2 (Tarsounas et al., 2003).
