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

The timeless (tim) gene is essential for circadian function in Drosophila. Putative homologues of Drosophila tim have been identified in both mice and humans (mTim and hTIM, respectively). Mammalian TIM is not the true orthologue of Drosophila TIM, but is the likely orthologue of a fly gene, timeout (also called tim-2) [1]. mTim has been shown to be essential for embryonic development, but does not have substantiated circadian function[2]. This entry corresponds to the PAB (PARP-1-binding domain) [3].	Domain
