Predicted to enable GTP binding activity and GTPase activity. Involved in several processes, including intraciliary transport; smoothened signaling pathway; and spermatogenesis. Acts upstream of or within cochlea development and inner ear receptor cell stereocilium organization. Located in centrosome; cytoplasm; and sperm flagellum. Part of intraciliary transport particle B. Is expressed in skin and yolk sac mesenchyme. Human ortholog(s) of this gene implicated in Bardet-Biedl syndrome 19. Orthologous to human IFT27 (intraflagellar transport 27).
