MACRO DOMAINS ARE ADP-RIBOSE BINDING MOLECULES

Overview

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.
