Predicted to be involved in olfactory behavior; positive regulation of flagellated sperm motility; and response to odorant. Predicted to be located in motile cilium. Predicted to be active in non-motile cilium and sperm midpiece. Human ortholog(s) of this gene implicated in spermatogenic failure 24. Orthologous to human CFAP69 (cilia and flagella associated protein 69).
