Predicted to enable dynein intermediate chain binding activity. Predicted to be involved in cilium movement; inner dynein arm assembly; and outer dynein arm assembly. Predicted to act upstream of or within cell projection organization. Located in cytoplasm. Is expressed in several structures, including genitourinary system; heart; liver; lung; and spleen. Human ortholog(s) of this gene implicated in primary ciliary dyskinesia 18. Orthologous to human DNAAF5 (dynein axonemal assembly factor 5). [provided by Alliance of Genome Resources, Apr 2022]
