Abstract
ADP-ribosylation (ADPr) is a widespread post-translational modification (PTM) spanning all kingdoms of life. It is employed by bacteria and viruses in their war against the host, and by eukaryotes to regulate many physiological processes, across almost all cellular compartments. PARP1, the founding member of the PARP family, is an early sensor of single- and double-strand breaks and catalyzes ADPr to mediate DNA damage repair. The recent discovery of Serine-ADPr and the PARP1 accessory factor HPF1 has brought a momentous change to the field. Bolstered by innovative ways to study ADPr, new and exciting research directions are rapidly emerging. In this review we explore our understanding of the HPF1/PARP1-mediated ADPr signaling pathway in DNA damage. We focus on the mechanistic steps leading to Serine-ADPr and its relevance in the DNA damage response. We discuss important technological advances that have enabled a nuanced study of Serine-ADPr, and conclude with an overview of the role of PARP inhibitors in cancer therapy.
期刊介绍：
DNA Repair provides a forum for the comprehensive coverage of DNA repair and cellular responses to DNA damage. The journal publishes original observations on genetic, cellular, biochemical, structural and molecular aspects of DNA repair, mutagenesis, cell cycle regulation, apoptosis and other biological responses in cells exposed to genomic insult, as well as their relationship to human disease.
DNA Repair publishes full-length research articles, brief reports on research, and reviews. The journal welcomes articles describing databases, methods and new technologies supporting research on DNA repair and responses to DNA damage. Letters to the Editor, hot topics and classics in DNA repair, historical reflections, book reviews and meeting reports also will be considered for publication.
