CC -!- FUNCTION: Required for oocyte nuclear envelope breakdown before entry
CC of oocyte into spermatheca (PubMed:10660671). In meiotic cells,
CC required for spindle dynamics and probably for spindle attachment to
CC the chromosomes (PubMed:10660671). Zygotic role in the development of
CC the germline and nerve cord (PubMed:10660671). In mitotic cells, plays
CC a role in spindle organization and centrosome maturation
CC (PubMed:20823068). Involved in asymmetric nuclear localization of cdc-
CC 25.1 during embryogenesis which affects cell division timing
CC (PubMed:18305005, PubMed:18316412, PubMed:20823068). Together with plk-
CC 2, regulates cytoplasm polarity in early embryos (PubMed:18199581,
CC PubMed:18316412, PubMed:18305005). May play a minor role in chromosome
CC pairing and synapsis during oocyte meiosis I (PubMed:22018922).

CC metaphase plate. In meiosis, detected at centrosomes after pronuclear
CC meeting in post-meiotic 1-cell embryos. Associated with chromatin
CC during chromosome segregation of anaphase and in the region between the
CC dividing chromosomes. Cytoplasmic in mature, unfertilized oocytes
CC (PubMed:10660671). Asymmetric cytoplasmic localization is regulated by
CC mex-5 and mex-6 (PubMed:18199581, PubMed:18316412).
