Predicted to enable actin binding activity. Predicted to be involved in actin cytoskeleton organization. Predicted to be located in cytosol and nucleus. Is expressed in adult brain; anterior midgut primordium; embryonic/larval midgut; and posterior midgut primordium. Human ortholog(s) of this gene implicated in Parkinson's disease; artery disease (multiple); brain disease (multiple); and multiple sclerosis. Orthologous to several human genes including PHACTR1 (phosphatase and actin regulator 1).
