The beauty of ADP-ribosylation: versatility in every link and organelle
摘要
ADPr is a crucial modification that regulates various cellular processes. Its complexity stems from the diverse chemical linkages it can form, including connections to various amino acids and nucleic acid components. ADPr can manifest as single ADP-ribose unit or as chains and can also form hybrid modifications. Here we focus on the remarkable versatility of ADPr and the distinct subcellular localization of its writers, which enable it to regulate essential processes in a spatiotemporal manner.
