Involved in establishment of cell polarity; regulation of cilium assembly; and tube formation. Acts upstream of or within microtubule organizing center organization and neuron migration. Located in cytoplasm; microtubule organizing center; and photoreceptor cell cilium. Is expressed in brain. Human ortholog(s) of this gene implicated in Bardet-Biedl syndrome 16 and Senior-Loken syndrome. Orthologous to human SDCCAG8 (SHH signaling and ciliogenesis regulator SDCCAG8).
