Although centriole satellites are involved in centrosome and ciliumrelated protein trafficking, their functions related to ciliary assembly and maintenance of ciliary microtubule stability remain unclear. In this study, the function of the FOP gene in Euplotes amieti was investigated by interfering with its expression using RNAi. As a result, expression levels of the ciliary assembly-related proteins BBS8 and IFT88 were down-regulated. Swimming speeds also decreased and the Euplotes were only able to spin in circles, which suggested that the FOP protein is an important protein involved in ciliary motion. Further observations of Euplotes amieti microstructure and ultrastructure via immunofluorescence and transmission electron microscopy revealed that FOP not only participated in the formation of the ventral ciliary basal body but also played an important role in the maintenance of cortical microtubules, which is fundamental for the morphological structure of Euplotes amieti.
