业已证实子孢子和裂殖子表面固有的或由特定细胞器赋于虫体表面的一些蛋白作为配体与宿主细胞表面受体结合。氨基酸序列分析提供了与入侵过程有关的一级结构基序。环子孢子蛋白和最初定位于微线体的子孢子表面蛋白-2含有可介导识别肝细胞表面硫酸多糖的氨基酸序列;裂殖子表面蛋白-1可能与红细胞的识别有关,这种蛋白在合成和侵入红细胞过程中进行了一系列复杂的修饰。其他位于裂殖子顶端的蛋白为红细胞或网织红细胞的结合蛋白。
It has been confirmed that sporozoites and merozoites on the surface, or by specific organelles assigned to the surface of parasites as a ligand and host cell surface receptors. Amino acid sequence analysis provides the primary structural motif involved in the invasion process. Circumsporozoite protein and the sporozoite surface protein-2 originally located on the microtubule contain an amino acid sequence that can mediate the identification of sulfated polysaccharides on the surface of liver cells; merozoite surface protein-1 may be involved in the identification of erythrocytes, A series of complex modifications were performed during the synthesis and invasion of erythrocytes. Other proteins located at the apical merozoites are red blood cells or reticulocyte binding proteins.
