Background: TEM8/ANTXR1

Anthrax toxin receptor 1 (ANTXR1), also known as Tumor endothelial marker 8 (TEM8), is a glycoprotein of the Anthrax Toxin Receptor family that is expressed by endothelial cells. TEM8/ANTXR1 contains a 289 amino acid (aa) extracellular domain, a 21 aa transmembrane domain, and a 222 aa cytoplasmic domain. Isoforms diverging at the C-termiuns include 564 aa (80‑85 kDa), 368 aa (60 kDa), and potentially secreted isoforms of 330 aa and 297 aa (45 kDa) (1). The extracellular domain shares structural similarity with von Willebrand factor type (vWFA) domains, which are characterized by their interactions with ECM components (2, 3). The extracellular domain is involved in reorganization of cell actin cytoskeleton (2, 3). TEM8/ANTXR1 binds Anthrax Protective Antigen with lesser affinity that Anthrax Receptor 2 and induces toxin internalization (4). TEM8/ANTXR1 has been implicated in tumor angiogenesis, as its expression has been shown to up-regulate in tumor blood vessels and is characterized as a tumor endothelial marker (5). TEM8/ANTXR1 was reported to be an amplifier of Wnt signaling in tumor microenvironment (6). Additionally, TEM8/ANTXR1 serves as the receptor for Seneca Valley virus, an oncolytic picornavirus affecting neuroendocrine cancers (7). Mouse TEM8/ANTXR1 shares 99% and 100% aa identity with human and rat TEM8/ANTXR1, respectively, within the extracellular domain.
