Predicted to be involved in axonemal dynein complex assembly and sperm axoneme assembly. Predicted to be active in centrosome and cytoplasm. Is expressed in dorsal sensory complex proper primordium; embryonic head sensory system; sensory nervous system primordium; and ventral sensory complex primordium. Human ortholog(s) of this gene implicated in acute lymphoblastic leukemia; alcohol dependence; drug dependence (multiple); nicotine dependence; and primary ciliary dyskinesia 45. Orthologous to human TTC12 (tetratricopeptide repeat domain 12).
