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. Predicted to be located in axoneme and sperm principal piece. Predicted to be part of outer dynein arm. Human ortholog(s) of this gene implicated in spermatogenic failure 46. Orthologous to human DNAH8 (dynein axonemal heavy chain 8). [provided by Alliance of Genome Resources, Apr 2022]
