Required for DNA double-strand breaks (DSBs) formation during meiotic recombination. Regulates the spatial and temporal patterns of pre-DSB recombinosome assembly and recombination activity by acting as a scaffold that anchors REC114 and other factors to specific genomic locations, thereby regulating DSB formation. Plays a key role in recombination in the pseudoautosomal regions of sex chromosomes. Interacts with REC114; the interaction is direct. Interacts with IHO1. Localizes on chromatin between preleptotene and early pachytene. Associates with the chromosome axes, but disappears from axes upon synaptonemal complex formation.
