Cilium- and flagellum-associated protein (PubMed:29606301). In the olfactory epithelium, regulates the speed of activation and termination of the odor response and thus contributes to the robustness of olfactory transduction pathways (By similarity). Required for sperm flagellum assembly and stability (PubMed:29606301). . This is the function of CFAP69 (cilia and flagella associated protein 69, Ensembl gene identifier ENSG00000105792).
