Fig. 1From: Genetic polymorphism of the extracellular region in surface associated interspersed 1.1 gene of Plasmodium falciparum field isolates from ThailandAmino acid sequences alignment of SURFIN4.2, SURFIN4.1, SURFIN1.3, and SURFIN1.1. The regions of SURFINs included extracellular (N-ter, CRD, Var1, and Var2), transmembrane (TM), and intracellular regions. Cysteine residue was marked in red box. A short conserved polar amino acid sequences were marked in blue box. The extra five amino acids in SURFIN1.1 were marked with red underlined. PEXEL and PEXEL-like sequences were marked with brown underlined.* = Identity amino acid, : = Highly conserved amino acid, · = Semi-conserved amino acidBack to article page
