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. Predicted to act upstream of or within cilium movement. Predicted to be part of inner dynein arm. Is expressed in choroid invagination; diencephalon roof plate; medulla oblongata part of 4th ventricle choroid plexus; metencephalon part of 4th ventricle choroid plexus; and node. Orthologous to human DNAH6 (dynein axonemal heavy chain 6). [provided by Alliance of Genome Resources, Apr 2022]
