ATAD1 and malaria: However, antibody reactivity against proteins representing some of the leading malaria vaccine candidates circumsporozoite protein (CSP, PFC0210c), merozoite surface protein 1 (MSP-1, PFI1475w), merozoite surface protein 2 (MSP-2, PFB0300c), apical membrane antigen 1 (AMA-1, PF11_0344) and liver stage antigen 3 (LSA3, PFB0915w) did not discriminate between protected and susceptible children (FDR > 0.05) (Fig. 6).
