A conserved DNA recombinase mediator complex that contains two Swi5 monomers and one Sfr1 monomer in Schizosaccharomyces, or orthologs thereof (e.g. Sae3p and Mei5p in Saccharomyces).
Comment:
Note that this term refers to Schizosaccharomyces pombe Swi5, which should not be confused with the unrelated Saccharomyces Swi5p.
