Involved in non-motile cilium assembly. Acts upstream of or within several processes, including osteoblast proliferation; receptor localization to non-motile cilium; and skeletal system development. Located in 9+0 non-motile cilium; centrosome; and ciliary basal body. Part of intraciliary transport particle B. Is expressed in diencephalon lateral wall ventricular layer; hypothalamus ventricular layer; midbrain ventricular layer; olfactory cortex ventricular layer; and telencephalon ventricular layer. Used to study asphyxiating thoracic dystrophy 2 and asphyxiating thoracic dystrophy 3. Human ortholog(s) of this gene implicated in asphyxiating thoracic dystrophy 2. Orthologous to human IFT80 (intraflagellar transport 80). [provided by Alliance of Genome Resources, Apr 2022]
