PF3D7_0918000 glideosome-associated protein 50 secreted acid phosphatase

Immunofluorescent staining of GFP-tagged GAP45 variants with GAP50 in late stage schizonts. (A) Parasites were fixed and the location of GFP (green) and GAP50 (red), examined. FL-GAP45, C-GAP45 and N-GAP45 all appear to colocalise with GAP50 in segmented schizonts. (B) Staining with anti-MSP1 antibody (red) colocalises with only N-GFP in developing schizonts. FL-GAP45 AND C-GAP45 are present in distinctive ring-shaped structures at the periphery of the developing schizont. (C) In mature schizonts MSP1 (red) is present on membranes surrounding the residual body. N-GAP45 is also present on the residual body, but FL-GAP45 and C-GAP45 are absent. The white arrow in all images indicates the residual body. These data are consistent with a plasma membrane location for N-GAP45 and an inner membrane complex location for FL-GAP45. In all cases, parasite nuclei were stained with DAPI (blue); merged images are also shown. Scale bar is 2 mm.
