Enables RNA binding activity. Involved in several processes, including cytoskeleton organization; positive regulation of double-strand break repair via homologous recombination; and positive regulation of meiotic nuclear division. Acts upstream of or within several processes, including embryo implantation; establishment or maintenance of apical/basal cell polarity; and in utero embryonic development. Located in apical part of cell; cell cortex; and nucleus. Part of subcortical maternal complex. Is expressed in several structures, including early conceptus; nervous system; nose; ovary; and skeleton. Orthologous to human OOEP (oocyte expressed protein).
