Predicted to enable calcium-dependent protein serine/threonine phosphatase regulator activity. Acts upstream of or within several processes, including calcineurin-NFAT signaling cascade; locomotion involved in locomotory behavior; and short-term memory. Predicted to be active in cytoplasm and nucleus. Is expressed in central nervous system; heart; and retina. Orthologous to human RCAN2 (regulator of calcineurin 2).
