Predicted to enable solute:proton antiporter activity and voltage-gated chloride channel activity. Involved in non-motile cilium assembly. Is active in ciliary base. Is expressed in early conceptus; heart; heart ventricle; and oocyte. Human ortholog(s) of this gene implicated in Raynaud-Claes syndrome. Orthologous to human CLCN4 (chloride voltage-gated channel 4). [provided by Alliance of Genome Resources, Apr 2022]
