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}.
