Plays a role in meiosis, germline development and oocyte morphogenesis (PubMed:28696027). May play a role in DNA replication (PubMed:28696027). In the germline, involved in the maintenance of transition zone nuclei and in chromosome structure and organization, but not required for mitotic proliferation (PubMed:28696027). Expressed in embryos. RNAi-mediated knockdown results in embryonic lethality in 10% of animals (PubMed:28696027). Surviving animals have a reduced brood size and abnormal diakinetic oocyte morphology (PubMed:28696027).
