Names

Common Name: ANTXR1 Type: Gene
Chromosome: 2 (NC_000002.12) Locus: NG_012649.1 (ANTXR1)
HUGO Symbol: ANTXR1 Full Name: anthrax toxin receptor 1
Exons: 18 Introns: 17

Description:
The ANTXR1 gene encodes a type I transmembrane protein with a single membrane-spanning domain that also serves as a cellular receptor for the anthrax toxin. The encoded protein contains an extracellular domain, which is highly similar to the von Willebrand factor type A (VWA) domain, with a metal ion-dependent adhesion site (MIDAS) motif required for ligand binding. The protective antigen (PA) component of the Bacillus anthracis toxin binds to the VWA domain for toxin entry in the cytosol. ANTXR1 is ubiquitously expressed and its normal functions are mainly associated with binding to extracellular matrix components, suggesting a role in adhesion and migration of cells. ANTXR1 is also known as Tumor Endothelial Marker 8 (TEM8) based on its selective upregulation in tumour-associated endothelial cells. ANTXR1 is implicated in events associated with angiogenesis. Loss-of-function mutations in the ANTXR1 gene associated with GAPO syndrome manifestations. Polymorphisms in this gene associated with high levels of HbF in cohorts of Saudi AI haplotype homozygotes but not in other sickle cell anaemia (SCA) populations. It is presumed that the effect of ANTXR1 on HbF regulation may stem from changes in Wnt signalling during hematopoiesis and/or interaction with HDAC enzymes.
