CC   -!- FUNCTION: Involved in DNA repair and in homologous recombination. May
CC       regulate the cleavage reactions of the branch-structured DNA. Has a
CC       very weak ATPase activity that is not stimulated by DNA. Binds DNA but
CC       does not promote DNA strands exchange (By similarity). {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the eukaryotic RecA-like protein family. RadB
CC       subfamily. {ECO:0000305}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=CAC12165.1; Type=Erroneous initiation; Evidence={ECO:0000305};
