Oocyte-specific protein that localizes to centromeres at the dictyate stage and regulates the survival of primordial oocytes. Localized to the synaptonemal complex lateral elements in late diplotene oocytes, while it is absent on the synaptonemal complex of leptotene, zygotene, pachytene and early diplotene oocytes (By similarity). Localizes to centromeres in dictyate oocytes (By similarity). Detected in nuclear granules and sizable aggregates (PubMed:17374641). Expressed in the ovary (at protein level). Belongs to the SYCP2 family.
