General Information

EC Number General Information Comment Organism
3.4.24.83 physiological function the anthrax toxin triggers tyrosine phosphorylation of its own receptors, capillary morphogenesis gene 2 and tumor endothelial marker 8, which is required for efficient toxin uptake. Phosphorylation of the receptors is dependent on src-like kinases, which are activated upon toxin binding. src-Dependent phosphorylation of the receptor is required for its subsequent ubiquitination, which in turn is required for clathrin-mediated endocytosis. Uptake of the anthrax toxin and processing of the lethal factor substrate MEK1 are inhibited by silencing of src and fyn, as well as in src and fyn knockout cells Bacillus anthracis
