A cholera toxin mutant (CTX-K63) unable to raise cAMP levels was used to study in Vero cells the retrograde transport of the toxin A subunit (CTX-A-K63), which possesses a COOH-terminal KDEL retrieval signal. Microinjected GTP-gamma-S inhibits the internalization as well as Golgi-ER transport of CTX-A-K63. The appearance of CTX-A-K63 in the Golgi induces a(More)
Retrograde traffic between the Golgi apparatus and the endoplasmic reticulum (ER) is largely mediated by COPI-coated transport vesicles. In mammalian cells, retrograde traffic can pass through an intermediate compartment. Here, we report that the mammalian soluble N-ethylmaleimide-sensitive factor (NSF) attachment receptor (SNARE) proteins mSec22b,(More)
