In the first mitotic division in embryos, required for mitotic spindle alignment and asymmetric cell division (PubMed:9649522, PubMed:17947426). Required for motor-driven chromosome movement and homolog searching within the nucleus, and subsequently ensures homologous chromosome pairing during the prophase stage of meiosis (PubMed:23671424). Localizes to mitochondria throughout interphase and mitosis (PubMed:17947426, PubMed:23671424). Localizes to mitochondria in the pachytene and transition zone regions of the germ cells (PubMed:23671424). Expressed in embryos.
