RL   Cell Rep. 14:1841-1849(2016).
CC   -!- FUNCTION: Plays a role in motile cilium function, possibly by acting on
CC       outer dynein arm assembly (PubMed:26904945). Seems to be important for
CC       initiation rather than maintenance of cilium motility (By similarity).
CC       Required for correct positioning of the cilium at the apical cell
CC       surface, suggesting an additional role in the planar cell polarity
CC       (PCP) pathway (PubMed:26904945). May suppress canonical Wnt signaling
CC       activity (PubMed:26904945). {ECO:0000250|UniProtKB:Q6DRC3,
CC       ECO:0000269|PubMed:26904945}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000269|PubMed:26904945}.
CC       Cytoplasm, cytoskeleton, cilium basal body
CC       {ECO:0000269|PubMed:26904945}. Note=Appears in cytoplasmic puncta,
CC       compatible with a centrosomal localization (By similarity).
CC       {ECO:0000250|UniProtKB:Q5U3Z0}.
CC   -!- DISRUPTION PHENOTYPE: Morpholino knockdown of the protein results in
CC       loss of cilia-driven fluid flow along the anterior-posterior axis.
CC       Multiciliated cells show loss of coordinated cilium polarity with many
CC       cilia pointing towards the anterior instead of the posterior. The
CC       planar cell polarity (PCP) component prickle2 is uniformly distributed
CC       around the cell margin, instead of being asymmetrically localized to
CC       the posterior of the cell. {ECO:0000269|PubMed:26904945}.
CC   -!- SIMILARITY: Belongs to the CFAP298 family. {ECO:0000305}.
