Amastin family. Topological model of subfamilies β- and δ-amastins from Trypanosoma cruzi. Amastins models share four predicted transmembrane helices and two extracellular hydrophilic loops. Although both N- and C-termini are predicted to be facing the cytoplasmic space, their length is variable among them. Topology predictions were performed using the “TOPO2, transmembrane protein display software” (http://www.sacs.ucsf.edu/TOPO2).
