Predicted to enable ATPase-coupled intramembrane lipid transporter activity. Acts upstream of or within neuron projection development. Predicted to be located in Golgi apparatus and nucleoplasm. Predicted to be active in plasma membrane. Human ortholog(s) of this gene implicated in cerebellar ataxia, mental retardation and dysequlibrium syndrome. Orthologous to human ATP8A2 (ATPase phospholipid transporting 8A2). [provided by Alliance of Genome Resources, Apr 2022]
