IPSE/alpha-1 triggers the release of IL-4 from basophils in the liver which is a major site of egg deposition during S. mansoni infection. This domain adopts a beta gamma-crystallin fold that is stabilized by three disulfide bonds within the domain (23/26, 59/93, and 111/121). The domain is involved in immunoglobulin binding [1].
