Background

Phosphoribosylformylglycinamidine synthase (PFAS) is a metabolic enzyme (deamidase) associated with a protein complex known as the “purinosome,” which is involved in de novo 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 de novo 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).

Species Reactivity

Species reactivity is determined by testing in at least one approved application (e.g., western blot).

Western Blot Buffer

IMPORTANT: For western blots, incubate membrane with diluted primary antibody in 5% w/v nonfat dry milk, 1X TBS, 0.1% Tween® 20 at 4°C with gentle shaking, overnight.

PFAS (E4M7R) Rabbit mAb

Western Blotting Image 1: PFAS (E4M7R) Rabbit mAb Expand Image
Western blot analysis of extracts from various cell lines using PFAS (E4M7R) Rabbit mAb (upper) and GAPDH (D16H11) XP® Rabbit mAb #5174 (lower). Expression levels of PFAS among cell lines are consistent with expectations based on publicly available bioinformatic databases, confirming specificity of the antibody for PFAS.
