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 microtubule-based movement and outer dynein arm assembly. Located in sperm principal piece. Is expressed in brain and thymus primordium. Used to study spermatogenic failure 46. Human ortholog(s) of this gene implicated in spermatogenic failure 46. Orthologous to human DNAH8 (dynein axonemal heavy chain 8).
