Predicted to be involved in axonemal dynein complex assembly; cilium-dependent cell motility; and regulation of cilium movement. Predicted to act upstream of or within determination of left/right symmetry and heart development. Predicted to be located in motile cilium. Predicted to be part of axonemal dynein complex. Predicted to be active in axoneme and cytosol. Human ortholog(s) of this gene implicated in primary ciliary dyskinesia 21. Orthologous to human DRC1 (dynein regulatory complex subunit 1).
