PF3D7_1328800 transcriptional regulatory protein sir2a

Immunofluorescence assay in paraformaldehyde fixed ring-stage parasites with anti-PfSir2a antibodies (red) in wild-type parasites (first row) and anti-mCherry antibodies (red) in 3D7DSir2aĆ¾Sir2aHmCherry parasites (second row). Nuclei of ring-stage parasites were stained with DAPI (blue). Scale bar, 1 mm. PfSir2aHmCherry was enriched at the nuclear periphery, forming foci that resemble the perinuclear pattern (telomeric clusters and nucleolus) previously shown for the native PfSir2a.
