Poly(ADP-ribose)-binding zinc finger motifs in DNA repair/checkpoint proteins.
Post-translational modification (PTM) of proteins plays an important part in mediating protein interactions and/or the recruitment of specific protein targets. PTM can be mediated by the addition of functional groups (for example, acetylation or phosphorylation), peptides (for example, ubiquitylation or sumoylation), or nucleotides (for example, poly(ADP-ribosyl)ation). Poly(ADP-ribosyl)ation often involves the addition of long chains of ADP-ribose units, linked by glycosidic ribose-ribose bo...Expand abstract
