Involved in several processes, including positive regulation of fertilization; positive regulation of flagellated sperm motility; and response to odorant. Acts upstream of or within sperm axoneme assembly. Located in non-motile cilium. Is expressed in several structures, including brain; genitourinary system; gut gland; nasal cavity epithelium; and spinal cord ventricular layer. Used to study spermatogenic failure 24. Human ortholog(s) of this gene implicated in spermatogenic failure 24. Orthologous to human CFAP69 (cilia and flagella associated protein 69). [provided by Alliance of Genome Resources, Apr 2022]
