Predicted to be involved in cilium assembly; protein localization to motile cilium; and reproductive system development. Predicted to act upstream of or within several processes, including epithelial cilium movement involved in extracellular fluid movement; flagellated sperm motility; and male gonad development. Predicted to be located in apical cytoplasm; cilium; and cytosol. Predicted to be active in cytoplasm. Human ortholog(s) of this gene implicated in primary ciliary dyskinesia 19. Orthologous to human DNAAF11 (dynein axonemal assembly factor 11). [provided by Alliance of Genome Resources, Apr 2022]
