PF3D7_0501300 skeleton-binding protein 1

Morphology of young Maurer’s clefts in ring-infected HbAA erythrocytes. Representative electron-microscopic images of parasitized erythrocytes preserved by: A. cryo-preservation; B. high pressure freezing and freeze-substitution. Post staining with uranyl acetate revealed a densely packed protein coat surrounding the membrane of the Maurer’s cleft. C. Immuno-electron micrograph of cells preserved by high pressure freezing and freeze substitution, and immuno-labelled with an antiserum to PfSBP1 coupled to 10 nm protein A colloidal gold. D. Section through a cyro-electron tomogram (left) and corresponding surface rendered view (right) of a Maurer’s cleft precursor in a ring-infected erythrocyte. Labeling and color code as following: PM, erythrocyte plasma membrane (dark blue); MC, Maurer’s cleft precursor (cyan); P, parasite (boundary of parasite, green), actin filaments (yellow) indicated by arrowheads. Scale bars, 100 nm in all images.
