Required both for recombination and for the repair of DNA damage caused by X-rays. Its function may be modulated by interaction with other repair proteins. RAD52 interacts directly with RAD51, via its C-terminus. Forms a nucleoprotein filament with DNA as an early intermediate in recombination. Part of a repair/recombination complex that includes RAD51, RAD52 and RAD54. Interacts with HED1, RDH54 and SAW1. Localizes as foci on meiotic chromosomes. RAD51 is cell cycle regulated, peaking around the G1-to-S transition. By X-rays. Present with 6960 molecules/cell in log phase SD medium. Belongs to the RecA family. RAD51 subfamily.
