Poly(ADP-ribose) polymerase catalyses the covalent attachment of ADP-ribose units from NAD+ to itself and to a limited number of other DNA binding proteins, which decreases their affinity for DNA. Poly(ADP-ribose) polymerase is a regulatory component induced by DNA damage. The carboxyl-terminal region is the most highly conserved region of the protein. Experiments have shown that a carboxyl 40 kDa fragment is still catalytically active [2].	Domain

ARTDs catalyse the formation of branched or unbranched chains of ADP-ribose units on protein side chains. The N-terminal domain of ARTD ...	This is the N-terminal domain of poly ADP-ribose polymerase (PARP16 also known as ARTD15) present in homo sapiens. ARTDs catalyse the formation of branched or unbranched chains of ADP-ribose units on protein side chains. The N-terminal domain of ARTD15 does not share any obvious sequence similarity with the regulatory domains of ARTD1-4. The N-terminal domain arrangement in both ARTD15 and ARTD1-3 suggests a regulatory role through different mechanisms [1].	Domain
