DOI: 10.1111/imb.12556
Abstract: Although membrane‐bound alkaline phosphatases (ALPs) have been proposed as a receptor for Cry1Ac in a few lepidopteran species, their potential functions as a Cry2Ab receptor are yet to be verified. To determine if ALP2 also… read more here.

DOI: 10.1186/s13568-021-01270-0
Abstract: As a pore-forming toxin, activation, oligomerization and pore-formation were both required for the mode of action of Cry toxins. Previous results revealed that the helices α4–α5 of Domain I were involved in the oligomerization of… read more here.
