PF3D7_1220900 heterochromatin protein 1

PfTRZ is required for proliferation and telomere length homeostasis. a, Co-localization of PfTRZ and PfHP1 in 3D7/TRZGFP, 3D7/TRZGFP-ON

(+Shield-1) and 3D7/TRZGFP-OFF (−Shield-1) trophozoites. White frames refer to the magnified view in the rightmost images. Scale bar, 5 μm. Results are representative of three biological replicate experiments. PfTRZ-GFP-DD displayed the expected perinuclear expression pattern in 3D7/TRZGFP-ON parasites, but was barely detectable in parasites cultured in the absence of Shield-1 (3D7/TRZGFP-OFF).
