A second merozoite surface protein (MSP-4) of Plasmodium falciparum that contains an epidermal growth factor-like domain.

abstract：:Antibody responses against proteins located on the surface or in the apical organelles of merozoites are presumed to be important components of naturally acquired protective immune responses against the malaria parasite Plasmodium falciparum. However, many merozoite antigens are highly polymorphic, and antibodies indu...
