Predicted to enable actin binding activity and phosphoprotein phosphatase activity. Involved in several processes, including excitatory chemical synaptic transmission; modulation of chemical synaptic transmission; and positive regulation of AMPA glutamate receptor clustering. Located in cell leading edge; cytosol; and growth cone. Orthologous to human SSH1 (slingshot protein phosphatase 1). [provided by Alliance of Genome Resources, Apr 2022]
