Required for DNA double-strand breaks (DSBs) formation in unsynapsed regions during meiotic recombination. Probably acts by forming a complex with IHO1 and MEI4, which activates DSBs formation in unsynapsed regions, an essential step to ensure completion of synapsis. Required for spermatogenesis and oogenesis (By similarity).
Subcellular locations: Chromosome
Located in discrete foci on the axes of meiotic chromosomes. The number of foci is highest at leptonema and decreases at zygonema.
