Stage-specific expression and subcellular localization of PfPCNA proteins. (B and C) IFA was performed on glass slides containing parasite smears, which were treated with antibodies against PfPCNA1 (B) or PfPCNA2 (C). PfPCNA1 (green) shows nuclear foci formation in replicating trophozoite stage and multinucleate schizont stage, whereas PfPCNA2 (red) shows both nuclear and cytoplasmic diffuse staining. DAPI (blue) stains the nuclei. The IFA showed distinct nuclear foci of endogenous PCNA1 during trophozoite and schizont stages of the parasites (B). Interestingly, endogenous PfPCNA2 shows a more diffused pattern throughout the nucleus and cytoplasm (C).Mitra P, Banu K, Deshmukh AS, Subbarao N, Dhar SK.

Right panels: Stage-specific expression and subcellular localization of PfPCNA proteins. (D and E) PfPCNA1–GFP and PfPCNA2–GFP transgenic parasite lines were visualized using an Olympus confocal microscope and Olympus Fluoview software. PfPCNA1–GFP (D) predominantly shows nuclear punctate staining co-localized with DAPI. PfPCNA2–GFP (E) shows a diffuse staining pattern across the parasite including the nuclei stained with DAPI. PCNA1–GFP showed distinct nuclear foci similar to endogenous protein (2D). However, these foci were absent from PCNA2–GFP, where a diffuse staining pattern could be seen throughout the parasites with slight enrichment of PCNA2–GFP in the nucleus (E). :pwer left panel: PCNA1 marks the sites of active replication. Live cell imaging of PCNA1-GFP expressing parasites using high resolution confocal microscopy shows distinct PCNA1 foci associated with the nucleus (shown in blue, DAPI) in trophozoite stages of the parasites.Mitra P, Banu K, Deshmukh AS, Subbarao N, Dhar SK.
