PF3D7_1246200 actin I

Co-staining of PfSRP polypeptides with nucleolar marker PfNOP1, ER marker PfBiP and cytoplasmic marker Pfactin. (a, b and c) P. falciparum infected erythrocytes stained with anti-PfSRP antibodies (green), anti-PfNOP1 (red), anti-PfBiP (red) and anti-Pfactin (red) respectively. (d) localization of GFP fused SRP19 (green) with ER tracker (red). DAPI is used for nuclear staining (blue). A considerable overlap in staining was observed between three PfSRP polypeptides; PfSRP19, -14, and -9 with PfNOP1 and with PfBiP protein (a and b, i-iv). Importantly, considerable co-localization of PfSRP54 with PfNOP1 in early stages of parasite development i.e. merozoite and ring stages.
