A-B family of toxins consists of plant toxins such as ricin and bacterial toxins such as cholera. The A subunit is the enzymatic domain and the B subunit is the receptor binding domain. Commonly, these toxins bind to the target cell plasma membrane receptors through their B subunit followed by endocytosis and a transport to the endoplasmic reticulum (ER). Inside the ER, the A subunit dissociates from the rest of the toxin, unfolds and triggers the ER quality control mechanism of ER-associated degradation (ERAD). Most ERAD substrates are purged out of the ER into the cytosol for proteasomal degradation. However, …
