In our previous study, we tested a 1TEL-flex-vWa construct consisting of residues 47–124 of human translocation ETS leukaemia [the sterile alpha motif (SAM) domain] followed by an alanine residue and then residues 40–217 of human capillary morphogenesis gene 2 (CMG2)/anthrax toxin receptor 2 (ANTXR2) [the von Willebrand factor type A (vWa) domain] (Fig. 1 ▸a). The gene discussed is ANTXR2; the disease is leukemia.
