AZIN1 and cancer: Notable examples are the antizyme inhibitor 1 (AZIN1) ADAR1-dependent recoding that promotes cell proliferation and contributes to cancer progression8, recoding of NEIL1 (Nei Like DNA Glycosylase 1) that results in a 30-fold reduction in the thymine glycol cleavage rate when acting on duplex DNA9, and FLNA (Filamin A) recoding which regulates vascular contraction and diastolic blood pressure10.
