Predicted to enable dynein intermediate chain binding activity; dynein light intermediate chain binding activity; and minus-end-directed microtubule motor activity. Involved in cellular response to 3,3',5-triiodo-L-thyronine; cellular response to nerve growth factor stimulus; and spermatid development. Located in several cellular components, including manchette; neuronal cell body; and nuclear envelope. Human ortholog(s) of this gene implicated in Charcot-Marie-Tooth disease axonal type 2O; autosomal dominant non-syndromic intellectual disability 13; and spinal muscular atrophy with lower extremity predominance 1. Orthologous to human DYNC1H1 (dynein cytoplasmic 1 heavy chain 1). [provided by Alliance of Genome Resources, Apr 2022]
