Abstract |
Disassembly of the Golgi apparatus is elicited by the action of nordihydroguaiaretic acid (NDGA) and this disassembly is prevented by the activation of heterotrimeric G proteins. In the present study we showed that overexpression of Galpha(z) or Galpha(i2) significantly suppresses the disassembly of the Golgi apparatus induced by NDGA. Overexpression of Gbeta(1)gamma(2), on the other hand, had no effect on NDGA-induced Golgi disassembly. Galpha(z) neither blocked Golgi disassembly induced by brefeldin A or nocodazole, nor interfered with protein transport, suggesting its specificity on the action of NDGA. Our results suggest that the alpha subunits of heterotrimeric G proteins are responsible for the maintenance of the Golgi structure.
