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 cerebellum development; isoprenoid biosynthetic process; and ubiquinone biosynthetic process. Predicted to act upstream of or within regulation of body fluid levels. Predicted to be located in cytosol. Predicted to be part of transferase complex. Human ortholog(s) of this gene implicated in primary coenzyme Q10 deficiency 3. Orthologous to human PDSS2 (decaprenyl diphosphate synthase subunit 2). [provided by Alliance of Genome Resources, Apr 2022]
