Predicted to be involved in axonemal dynein complex assembly and motile cilium assembly. Predicted to act upstream of or within determination of left/right symmetry and heart development. Predicted to be located in dynein axonemal particle. Human ortholog(s) of this gene implicated in primary ciliary dyskinesia 2. Orthologous to human DNAAF3 (dynein axonemal assembly factor 3).
