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. Predicted to be located in several cellular components, including dynein axonemal particle; external side of plasma membrane; and sperm flagellum. Predicted to be part of outer dynein arm. 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]
