Catalyzes ADP-ribosylation of the G proteins Gαi, Gαo and Gαt
Toxin produced by Bordetella pertussis . Catalyzes ADP-ribosylation of the α subunits of the heterotrimeric Gi/o proteins; Gαi, Gαo and Gαt . Blocks receptor coupling and activation by preventing G protein heterotrimers from interacting with receptors.
This product is not activated. Cells will activate pertussis toxin in an intact system however activation is required in a cell free system. Incubation with high concentrations of dithiothreitol (DTT) can achieve activation, see Kaslow, et al. (1987) for suggested conditions.
