Predicted to enable dynein heavy chain binding activity; dynein light chain binding activity; and microtubule motor activity. Predicted to be involved in cilium movement; determination of left/right symmetry; and outer dynein arm assembly. Predicted to act upstream of or within cilium assembly. Located in 9+2 motile cilium; axoneme; and external side of plasma membrane. Is expressed in spermatozoon and testis. Used to study Kartagener syndrome and primary ciliary dyskinesia. Human ortholog(s) of this gene implicated in primary ciliary dyskinesia 9. Orthologous to human DNAI2 (dynein axonemal intermediate chain 2). [provided by Alliance of Genome Resources, Apr 2022]
