| Application: | Inactive toxin form released from B. pertussis. |
| Application: | Pertussis toxin from Bordetella pertussis has been used: as a blocker of the Gαi subunit of the chemokine (CXCR4) receptor to measure the intracellular Ca2+ in breast cancer cell lines, to characterize the Gi signaling involved in ADP-induced tissue factor (TF) and P-selectin exposure, to induce autoimmune vasculitis in a rat model |
| Application: | The toxin is released from B. pertussis in an inactive form. When the pertussis toxin B oligomer binds to the cell membrane, the S1 subunit of its A protomer becomes activated, perhaps through the action of glutathione and ATP. A protocol for activating pertussis toxin in vitro is given by Kaslow, et al. |
| Biochem/physiol Actions: | Pertussis toxin catalyzes the ADP-ribosylation of the α subunits of the heterotrimeric guanine nucleotide regulatory proteins Gi, Go, and Gt. |
| Biochem/physiol Actions: | Pertussis toxin catalyzes the ADP-ribosylation of the α subunits of the heterotrimeric guanine nucleotide regulatory proteins Gi, Go, and Gt. This prevents the G protein heterotrimers from interacting with receptors, thus blocking their coupling and activation. Since the Gα subunits remain in their GDP-bound, inactive state, they are unable to inactivate adenylyl cyclase or open K+ channels. |
