PfKMT1 and genes enriched in H3K9me3 are positioned at the nuclear periphery. Immuno-fluorescence assays using antibodies against H3K9me3 H3 (right) and the P. falciparum putative H3K9 methyltransferase PfKMT1 (left). 3D7 parasites are in late schizont (main image) and ring stage (top-right square). Nuclear DNA was detected with DAPI (red).
