PF3D7_0609800 palmitoyltransferase, putative

Detection of PfPATs (=DHHCs) by immunofluorescence assay in P. falciparum blood stage schizonts. Mouse antisera raised against unique peptides derived from PfPATs -1, -2, -3 and -7 were used for immunostaining of slides smeared with P. falciparum schizont stages. Pre-immune sera were used as negative control (not shown). Nuclei were stained with DAPI (blue). The scale bar represents 5μm. IFA shows that PfDHHC PAT -1, -2, -3 and -7 are expressed in schizonts with minimal staining observed at ring and trophozoite stages. Apical staining was observed for PfDHHC PAT -1, -2, -3 and 7 in daughter merozoites. Colocalisation studies with microneme protein PfAMA1 indicates these PfPATs are localized at the apical end of the merozoites. However, PfPATs do not overlap completely with PfAMA1.
