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