Predicted to enable dehydrodolichyl diphosphate synthase activity and polyprenyltransferase activity. Predicted to be involved in dolichyl diphosphate biosynthetic process and polyprenol biosynthetic process. Predicted to be part of dehydrodolichyl diphosphate synthase complex. Predicted to be active in endoplasmic reticulum. Human ortholog(s) of this gene implicated in developmental delay and seizures with or without movement abnormalities and retinitis pigmentosa 59. Orthologous to human DHDDS (dehydrodolichyl diphosphate synthase subunit). [provided by Alliance of Genome Resources, Apr 2022]
