In order to obtain the complete gene encoding the putative precursor of a 15-kDa Schistosoma mansoni tegumental antigen (Sm15), two cDNAs (A70 and A184) and two fragments of independent genomic clones were subcloned and sequenced. The collated sequence contains 4700 nucleotides and represents the full length open reading frame of the gene, encoding a protein of 1032 amino acids with a calculated molecular mass of 116,900. Thus, the gene encodes a much longer protein than that identified in the tegumental membranes, suggesting that it encodes a precursor that is subsequently highly processed. A 964-bp region composed of 5 closely related repeats was found to be present within the translated frame. The predicted protein is highly acidic and there is no indication of hydrophobic domains that may represent transmembrane regions or indicate attachment of a GPI anchor. The coding region has no homologies in the currently available data bases. In the 5' non-transcribed area a copy of the SM alpha repeat family is present. The coding region is preceded by putative CCAAT and TATA boxes that may be involved in the control of expression.
