Predicted to enable calcium-dependent protein serine/threonine phosphatase regulator activity and identical protein binding activity. Involved in several processes, including negative regulation of smooth muscle cell differentiation; response to estrogen; and skeletal muscle tissue development. Predicted to be active in cytoplasm and nucleus. Human ortholog(s) of this gene implicated in Alzheimer's disease. Orthologous to human RCAN1 (regulator of calcineurin 1).
