| Abstract | Toxoplasma gondii is a persistent protozoan parasite capable of infecting almost any warm-blooded vertebrate. The surface of T. gondii is coated with a family of developmentally regulated glycosylphosphatidylinositol (GPI)-linked proteins (SRSs), of which SAG1 is the prototypic member. SRS proteins mediate attachment to host cells and interface with the host immune response to regulate the virulence of the parasite. The structure of the immunodominant SAG1 antigen reveals a homodimeric configuration [ 9418898]. This family of surface antigens is found in other apicomplexans. |
