Co-localisation of H3-K79me3 with known cellular compartments. A. Nucleolus: Double labelling IFAs with antibodies against H3-K79me3 and nucleolus marker, PfNop1. B. Telomere clusters: IFeFISH analysis between H3-K79me3 (red) and Rep20 (green). C. Active var gene: IF-FISH analysis between H3-K79me3 (red) and active var gene (green). D. Active var gene colocalisation with activating mark, H3-K4me3. IF-FISH analysis between H3-K4me3 (red) and active var gene (green). DAPI stained nucleus in blue. Font colour represents corresponding fluorescein labelled antibody. Scale bar depicts 1 mm. E. Schematic of the dynamic compartmen-talisation of the P. falciparum nucleus. The distinct sub-nuclear distribution of histone methylation modification, taking example of H3-K79me3 as observed in this study. Known compartments compatible with active transcription are indicated. H3-K79me3 occupies a distinct zone.
