Required for meiotic induction of recombination, viable spore production and chromosome synapsis. Component of the MER2-MEI4-REC114 complex which seems to be required for meiotic double-strand break (DSB) formation. Interacts with MER2 and REC114. Component of the MER2-MEI4-REC114 complex. Localizes to chromosomes. Expressed only in meiosis.
