Predicted to enable dynein intermediate chain binding activity; dynein light intermediate chain binding activity; and minus-end-directed microtubule motor activity. Predicted to be involved in cilium-dependent cell motility and microtubule-based movement. Located in motile cilium. Is expressed in central nervous system. Human ortholog(s) of this gene implicated in spermatogenic failure 45. Orthologous to human DNAH2 (dynein axonemal heavy chain 2). [provided by Alliance of Genome Resources, Apr 2022]
