    ..These results suggest that Bru cooperates with Rab11 and PI4Kbeta to regulate the efficiency of membrane addition to the cleavage furrow, thus promoting cytokinesis in Drosophila male meiotic cells. ..

    ..Our data suggest that Aux participates in forming these Golgi-derived clathrin-positive vesicles and that Aux, therefore, has a role in the secretory pathway. ..
