PEXEL TM proteins require translocation for export and some PEXEL proteins can also jam the translocon. (A-C) Representative images of live P. falciparum parasites expressing the constructs shown schematically above each panel (numbers refer to the length of the amino acids sequence between TM and blocking domain). DIC, differential interference contrast. Size bars: 5 μm. A schematic of the co-block (B) and failure to coblock (C) are shown to the right.
