PRTFDC1 (Phosphoribosyl Transferase Domain Containing 1): PRTFDC1 is an enzyme involved in the purine salvage pathway, which recycles purines from degraded DNA and RNA to create new nucleotides. This role in nucleotide metabolism suggests it is important for cell proliferation and DNA repair. Changes in this pathway can impact cellular energy balance and genomic stability, with potential effects on metabolic health and DNA damage response.
