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 movement. Predicted to be located in cilium; cytoplasm; and microtubule. Predicted to be part of inner dynein arm. Is expressed in choroid invagination; diencephalon roof plate; metencephalon part of 4th ventricle choroid plexus; olfactory epithelium; and pharynx epithelium. Orthologous to human DNAH12 (dynein axonemal heavy chain 12). [provided by Alliance of Genome Resources, Apr 2022]
