Raft trafficking of AB5 subunit bacterial toxins.

Abstract

Cholera and the related AB(5)-subunit toxins co-opt plasma membrane (PM) glycolipids to move retrograde into the endoplasmic reticulum (ER) of the host cell where a portion of the toxin is retro-translocated to the cytosol to induce disease. Only glycolipids that associate strongly with detergent insoluble membrane microdomains can sort the toxins backwards… (More)
