Webbwe summarize the current understanding of ADP-ribosylation and the PARPs/ARTDs family proteins, in particular PARP1/ARTD1-conferred PARylation, in B cells. Following an overview of PARylation in cellular responses to environmental and spontaneous DNA damage, we discuss the emerging function of PARP1/ARTD1 and PARylation in DNA WebbPertussis toxin (PTX) catalyzes the ADP-ribosylation of the α-subunit of GTPbinding proteins (G-proteins) in the presence of NAD +. Pertussis toxin also decreases the electrophoretic mobility of the a-subunit on urea SDS PAGE. This effect of PTX has been suggested to be a property of the toxin different from its ability to catalyze ADP ...
