Enables dynein heavy chain binding activity. Predicted to act upstream of or within cilium movement. Located in several cellular components, including axoneme; ciliary base; and filopodium. Is expressed in several structures, including brain ventricle and choroid plexus; choroid invagination; ependyma; epithelium; and testis. Orthologous to human DNALI1 (dynein axonemal light intermediate chain 1). [provided by Alliance of Genome Resources, Apr 2022]
