Required for the assembly of axonemal inner and outer dynein arms. Involved in preassembly of dyneins into complexes before their transport into cilia. Mainly expressed in cell types that express axonemal dyneins. Static olfactory placode cilia; reduced movement of debris in the olfactory placode. The morphology and number of cilia in the olfactory placode is unaffected, but an abnormal ultrastructure in these cilia is observed, including reduced or missing outer and inner dynein arms. Belongs to the DNAAF3 family.
