PF3D7_1333700 histone H3-like centromeric protein CSE4

Right: PfSec13 does not co-localize with P. falciparum heterochromatin. IFAs of the PfSec13-GFP expressing parasites that were co-immunolabled with α-GFP (green) and α-H3K9me3 (red) at different stages of the IDC. In 85% of the counted nuclei of all stages (n=100), the H3K9me3 signal and PfSec13-GFP did not co-localize.

Left: In vivo imaging of parasites expressing both PfSec13-GFP and PfHP1-HA-mCherry during the IDC. Although PfSec13 (green) and PfHP1 (red) localized to the nuclear periphery they do not co-localize.

Righet lower corner: In vivo confocal microscopy of parasites expressing both PfSec13-GFP and PfHP1-HA-mCherry.
