GAP45 is required for invasion but not for microneme discharge. IFA showing relocalization of microneme protein AMA1 to the merozoite periphery in both mock-treated and ΔGAP45 parasites. Bar, 5 mm. IFA analysis of highly mature, segmented schizonts showed that translocation of AMA1 to the surface of ΔGAP45 parasites occurred as normal, indicating that microneme secretion is unaffected by the absence of GAP45.
