The Macro Domain is an Adp-Ribose Binding Module.
Embo J., 24:1911-, 2005

PubMed Abstract: The ADP-ribosylation of proteins is an important post-translational modification that occurs in a variety of biological processes, including DNA repair, transcription, chromatin biology and long-term memory formation. Yet no protein modules are known that specifically recognize the ADP-ribose nucleotide. We provide biochemical and structural evidence that macro domains are high-affinity ADP-ribose binding modules. Our structural analysis reveals a conserved ligand binding pocket among the macro domain fold. Consistently, distinct human macro domains retain their ability to bind ADP-ribose. In addition, some macro domain proteins also recognize poly-ADP-ribose as a ligand. Our data suggest an important role for proteins containing macro domains in the biology of ADP-ribose.
