CC   -!- FUNCTION: Cytoplasmic polyadenylation element binding protein that
CC       binds to and regulates the translation of specific mRNAs. Essential for
CC       progression through meiosis. Involved in spermatogenesis (By
CC       similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Interacts with fbf-1. {ECO:0000250}.
