Anthrax EF (edema factor) and LF (lethal factor) toxins bound to PA63:ANTXR1 (protective antigen, large fragment:Anthrax receptor 1) oligomer on the plasma membrane of the target cell, are localized into clathrin coated vesicles and transported to endosomes. Depletion of target cell ARAP3 (ArfGAP with RhoGAP domain, ankyrin repeat and PH domain 3) partly blocks endocytosis (Lu et al. 2004), but this effect may be indirect and has not been characterized at a molecular level (van der Goot & Young 2009).
