CC -!- FUNCTION: Plays an important role in DNA replication, recombination and
CC repair. Binds to ssDNA and to an array of partner proteins to recruit
CC them to their sites of action during DNA metabolism.
CC {ECO:0000255|HAMAP-Rule:MF_00984}.
CC -!- SUBUNIT: Homotetramer. {ECO:0000255|HAMAP-Rule:MF_00984}.
