Enables several functions, including CDP-diacylglycerol-inositol 3-phosphatidyltransferase activity; diacylglycerol binding activity; and manganese ion binding activity. Involved in CDP-diacylglycerol metabolic process and phosphatidylinositol biosynthetic process. Predicted to be integral component of membrane. Predicted to be active in Golgi apparatus. Orthologous to human CDIPT (CDP-diacylglycerol--inositol 3-phosphatidyltransferase). [provided by Alliance of Genome Resources, Apr 2022]
