Cytidine acetylation
WebJun 12, 2024 · Moreover, acetylation of the N 4 position of cytidine (ac4C) was recently reported to increase the translation and stability of cellular mRNAs. Here, we show that ac4C and N-acetyltransferase 10 (NAT10), the enzyme that adds ac4C to RNAs, have been subverted by human immunodeficiency virus 1 (HIV-1) to increase viral gene expression. WebNew Acetylation-Based Signaling Mechanisms Acetyl-CoA links metabolism and signaling by mediating protein and nucleic acid modifications known as acetylations, whose modulation is an emerging paradigm in cancer treatment.
