Background

Capillary Morphogenesis Gene-2 (CMG-2) is a widely expressed anthrax toxin receptor (ATR) family protein (1‑3). CMG-2 is a 55 kDa type I transmembrane (TM) protein that contains a 33 amino acid (aa) signal sequence, a 284 aa extracellular domain (ECD), a 24 aa TM segment, and a 147 aa cytoplasmic domain. There are three additional isoforms. Isoforms 4 shows a 12 aa insertion in the cytoplasmic region; isoform 2 shows a 103 aa deletion in the ECD; and isoform 3 is a truncated, 20 kDa, 289 aa soluble form. The main functional domain of CMG-2 is an extracellular integrin-like von Willebrand factor type A (VWA) domain with a metal ion dependent adhesion site (MIDAS). This domain adheres selectively to collagen type IV and laminin (1‑5). CMG-2 isoform 2 is induced in HUVEC as they undergo capillary formation in collagen matrices in vitro (3). CMG-2 is mutated in juvenile hyaline fibromatosis and infantile systemic hyalinosis disorders, and several of these mutations result in loss of laminin binding (6). CMG-2 and the related protein ATR/TEM8 serve as receptors for the protective antigen (PA) of Bacillus Anthracis (1, 2). After binding the VWA domain, PA undergoes furin-type cleavage, forms a heptameric receptor/PA pre-pore and binds LF or EF toxin subunits (5, 7, 8). Transport to low pH endosomes, which requires CMG-2 ubiquitination and interaction with the LDL receptor related protein LRP6 (9, 10), allows PA pore formation and release of toxin to the cytoplasm (10, 11). Soluble CMG-2 VWA domain acts as a dummy receptor that can protect cultured cells from anthrax intoxication (2). Within the extracellular region, human CMG-2 shares 84%, 81%,89% and 93% amino acid sequence homology with mouse, rat, bovine, and canine CMG-2, respectively. CMG-2 VWA domain also shares 60% aa identity with ATR/TEM8.
