Required for proper homologous chromosome pairing and efficient cross-over and intragenic recombination during meiosis. Stimulates both DMC1/LIM15- and RAD51-mediated homologous strand assimilation, which is required for the resolution of meiotic double-strand breaks. Interacts with HOP2, RAD51, LIM15 and MIP1. Localized to chromatin during meiosis. Expressed in reproductive tissues. Female and male sterility due to production of defective gametes. Belongs to the MND1 family.
