Abstract

A female-specific sequence was isolated from a cDNA library of Schistosoma mansoni and further characterizedSequences reported here are available from DDBJ/EMBL/GenBank under the Accession number Z27402.. Expression of the corresponding gene (p19) depends on pairing with a male. In situ hybridization and immunohistology experiments revealed exclusive expression of the gene in the cells of the vitellarium, suggesting a function in egg formation. In addition, experimental evidence for cross-linking of the protein under oxidative conditions supports the assumption that the p19 gene may code for an egg-shell precursor protein.
