title: Primary structure of a Plasmodium falciparum rhoptry antigen.
abstract: The high-molecular-weight rhoptry complex of Plasmodium falciparum consists of 3 non-covalently associated polypeptides of 150, 135 and 105 kDa. We present the complete nucleotide sequence of the 105-kDa (RhopH3) component of this complex derived from analysis of genomic and cDNA clones. The genomic structure is unusually complex for P. falciparum, consisting of 7 exons including 2 mini-exons of 19 and 21 amino acids. The sequence lacks tandem repeats and is conserved among several parasite isolates. B cell epitopes that induce antibody responses during natural infection were mapped to five different regions of the polypeptide.
