A Plasmodium falciparum gene encoding immunogenic SERA protein has been isolated by a) systematically screening a lambda gt11 recombinant DNA expression library with a murine monoclonal antibody directed against protein antigens of this pathogen, and b) systematically screening a lambda gt11 genomic cDNA and oligonucleotide probes directed against this pathogen. A 111 kDa protein has been shown to have immunogenic activity against parasite inhibitory antibodies. The gene encoding this protein, including the signal sequence and regulatory sequence in the adjacent 5′ flanking sequence has been isolated and sequenced. Isolation and characterization of genes encoding major protein antigens of P. falciparum make it possible to develop reagents useful in the diagnosis, prevention and treatment of malaria. In addition, the signal sequences or regulatory sequences of this gene can be used to stimulate the production of other useful genetic products.
