PF3D7_1133400 apical membrane antigen 1

PfSUB2 Is a Microneme Protein. (A) IFA images of schizonts of PfSUB2HA clone 2D dual-labelled with mAbs X509 (anti-MSP1), 61.3 (anti-RhopH2), or 4G2 (anti-AMA1), plus in each case mAb 3F10 (anti-HA) The anti-HA signal co-localised only with the anti-AMA1 signal. Identical results were obtained with the uncloned

transgenic PfSUB2HA line, and/or when anti-RAP2 mAb H5 was used as the rhoptry marker instead of mAb 61.3 (not shown). Parasite nuclei are stained throughout with DAPI (blue). Scale bar represents 2 mm. the anti-HA signal was quite different from that of MSP1, it was adjacent to but distinct from that of the rhoptry specific signals, but it co-localised completely with that of

AMA1, indicating that in mature schizonts, PfSUB2 accumulates in micronemes.
