Involved in primary cilium formation (PubMed:28530676). Probably acts as a transition zone protein required for localization of PKD1/PC1 and PKD2/PC2 to the ciliary membrane. Localizes to centrioles and to the distal ends of basal bodies. Maternally expressed. Ubiquitously expressed in embryos at 1 day post-fertilization (dpf), with a more discrete accumulation in the embryonic kidneys. In developing kidney, expressed in the midsections of the pronephric ducts, in a pattern consistent with the multiciliated cells. Embryos show defects in otolith formation in the inner ear, but no other overt morphological changes. Belongs to the DZIP C2H2-type zinc-finger protein family.
