During the asexual blood stage, recruits host complement factor H CFH to the surface of merozoites resulting in the down-regulation of the host complement alternative pathway and thus, protecting merozoites from complement-mediated lysis. Interacts with host complement factor CFH isoform 1 (via sushi 4-6 domains) and CFH isoform FHL-1 (via sushi 4-6 domains); this interaction recruits CFH onto the merozoite surface preventing complement-mediated cell lysis (PubMed:26700768). The interaction does not affect CFH activity (PubMed:26700768). Present on the surface of merozoite. Expressed during the parasite blood stage, specifically in schizonts (at protein level). In strain D10, causes a loss of binding of human CFH to the merozoite surface resulting in a 7-fold increase in host complement-mediated merozoite lysis.
