SEMP1 expression and localization. A: schematic representation of the semp1 gene(top) and SEMP1 protein structure (bottom).TM, transmembrane protein B: Live cell imaging of 3D7 parasites expressing SEMP1 with C-terminal-tagged GFP.C: Immunofluorescence assays of MeOH fixed RBCs infected with 3D7 expressing SEMP1 with a C-terminal 3xHA tag, co-labelled with rata-HA and either rabbit a-MAHRP1 or rabbit a-REX1 antibodies. D: Scatter plot of co-localization of SEMP1 and REX1 in SEMP1-3xHA parasites. E: Electronmicroscopy (EM) of RBCs infected with 3D7 expressing SEMP1 with a C-terminal GFP tag labelled with rabbit a-GFP antibodies and decorated with 5nm gold conjugated Protein A.
