PDSS1 (Prenyl (Decaprenyl) Diphosphate Synthase, Subunit 1): PDSS1 is a protein involved in the production of coenzyme Q10, a vital molecule in the mitochondrial electron transport chain. It plays an essential role in cellular energy generation and antioxidant defense. Dysfunction of PDSS1 can result in coenzyme Q10 deficiency, which may contribute to various neuromuscular and neurodegenerative disorders.
