Background Phosphoribosylformylglycinamidine synthase (PFAS) is a metabolic enzyme (deamidase) associated with a protein complex known as the "purinosome," which is involved in purine synthesis (1). Research studies have shown that activation of the MAPK/ERK pathway leads to downstream activation of PFAS. Specifically, it was shown that PFAS is a substrate of ERK2, which phosphorylates PFAS at Thr619; activation of PFAS results in the generation of purine intermediates required for cell and tumor growth (2). It has also been reported that both PFAS and viral PFAS-like proteins can activate RIG-I pattern recognition receptors, implicating PFAS-mediated deamidation in the innate immune response to viral infection (3).
