Predicted to be involved in axonemal dynein complex assembly; cilium-dependent cell motility; and epithelial cilium movement involved in extracellular fluid movement. Predicted to act upstream of or within several processes, including axonemal dynein complex assembly; establishment of left/right asymmetry; and response to retinoic acid. Predicted to be located in cytosol and dynein axonemal particle. Human ortholog(s) of this gene implicated in primary ciliary dyskinesia 10. Orthologous to human DNAAF2 (dynein axonemal assembly factor 2). [provided by Alliance of Genome Resources, Apr 2022]
