Required for the formation of DNA double-strand breaks (DSBs) together with nenya and vilya during the meiotic recombination process (PubMed:30615609). Plays a role in DSBs processing into crossovers (PubMed:30615609). Plays a redundant role with nenya in chromosome segregation during female meiosis (PubMed:30615609). May interact with itself, with nenya and vilya through its RING-type zinc finger. Localizes to DNA double-strand breaks during female meiosis in both nurse cells and pro-oocytes (PubMed:30615609). During early pachytene, colocalizes with vilya to the central region of the synaptonemal complex (SC) (PubMed:30615609). Expressed in nurse cell and pro-oocytes (at protein level). Nenya, narya and vilya contain a RING-type zinc finger domain and are named after the Three Rings of Power given by the elves of Eregion in J.R.R. Tolkien's books. Extended N-terminus.
