Schematic structure of SURFIN1.1 regions. The regions of SURFIN1.1 is comprised extracellular (aa 1–301), TM (aa 302–332), and intracellular region (aa 333–1555). The extracellular region of SURFIN1.1 was divided into four sub-regions. These sub-regions included N-ter (aa 1–55), CRD (aa 56–176), Var1 (177–236), and Var2 (aa 237–301)
