Description_x000D_ General description_x000D_ ANTXR1 is a type I transmembrane protein and is a tumor-specific endothelial marker that has been implicated in colorectal cancer. This protein has been shown to also be a docking protein or receptor for Bacillus anthracis toxin, the causative agent of the disease, anthrax. The binding of the protective antigen (PA) component, of the tripartite anthrax toxin, to this receptor protein mediates delivery of toxin components to the cytosol of cells. Once inside the cell, the other two components of anthrax toxin, edema factor (EF) and lethal factor (LF) disrupt normal cellular processes._x000D_ Immunogen_x000D_ ANTXR1 (NP_115584, 409-442)_x000D_ This antibody is generated from rabbits immunized with a KLH conjugated synthetic phosphopeptide corresponding to amino acid residues surrounding Y425 of human ANTXR1._x000D_ Physical form_x000D_ Purified polyclonal antibody supplied in PBS with 0.09% (W/V) sodium azide.
