Enables phospholipid scramblase activity. Acts upstream of or within calcium activated galactosylceramide scrambling and calcium activated phosphatidylcholine scrambling. Predicted to be located in membrane. Predicted to be integral component of membrane. Predicted to be active in plasma membrane. Is expressed in several structures, including alimentary system; apical ectodermal ridge; nervous system; sensory organ; and skeleton. Human ortholog(s) of this gene implicated in dystonia 24. Orthologous to human ANO3 (anoctamin 3). [provided by Alliance of Genome Resources, Apr 2022]
