Predicted to enable all-trans-decaprenyl-diphosphate synthase activity and protein heterodimerization activity. Predicted to contribute to trans-hexaprenyltranstransferase activity and trans-octaprenyltranstransferase activity. Predicted to be involved in isoprenoid biosynthetic process and ubiquinone biosynthetic process. Predicted to be part of transferase complex. Human ortholog(s) of this gene implicated in primary coenzyme Q10 deficiency 2. Orthologous to human PDSS1 (decaprenyl diphosphate synthase subunit 1).
