Required for the proper orientation of spindles after the establishment of polarity (PubMed:9477332, PubMed:14534135). May play a role in interactions between the astral microtubules and the cortical cytoskeleton (PubMed:9477332). Required for asymmetric forces on nuclei and spindles (PubMed:9477332). Acts downstream of the PAR signaling as an intermediate that transduces polarity information to the machinery that positions the mitotic spindle, possibly by regulating force generation (PubMed:12223405). Regulates gpr-1/2 asymmetric cortical localization during the first embryonic cell divisions (PubMed:14534135). Acts antagonistically to the gpr-1/2 signaling pathway (PubMed:14534135). Regulates mes-1 expression and/or localization pattern during early embryogenesis (PubMed:11003841). Enriched at the cell cortex during both meiosis and mitosis (PubMed:12223405). Enriched asymmetrically at the cell cortex in 1-cell embryos (PubMed:14534135). Localizes at the contact site between EMS and P2 in interphase and is excluded from the contact site during prophase (PubMed:14534135). Expressed both maternally and zygotically.
