Predicted to enable isopentenyl-diphosphate delta-isomerase activity. Predicted to be involved in isoprenoid biosynthetic process. Predicted to act upstream of or within isopentenyl diphosphate metabolic process and negative regulation of cholesterol biosynthetic process. Predicted to be located in peroxisome. Orthologous to human IDI2 (isopentenyl-diphosphate delta isomerase 2). [provided by Alliance of Genome Resources, Apr 2022]
