Predicted to be involved in regulation of cilium beat frequency and sperm axoneme assembly. Predicted to act upstream of or within several processes, including epithelial cilium movement involved in extracellular fluid movement; flagellated sperm motility; and motile cilium assembly. Predicted to be located in 9+2 motile cilium. Predicted to be active in axoneme. Human ortholog(s) of this gene implicated in normal pressure hydrocephalus and spermatogenic failure 19. Orthologous to human CFAP43 (cilia and flagella associated protein 43). [provided by Alliance of Genome Resources, Apr 2022]
