    Abstract:
    The major surface glycoprotein (MSG) of rat-derived Pneumocystis carinii represents a group of related molecules that are encoded by multiple genes. We isolated seven unique MSG cDNAs from a library prepared from a single infected rat lung. The cDNAs displayed both conserved and variant regions to previously described cDNAs. These clones contained inserts that ranged in size from 0.4 to 1.8 kb and all contained a poly(A) tail. The largest clone, Pc1410, hybridized to all 15 chromosomes resolved by pulsed-field gel electrophoresis (PFGE). Protein produced by in vitro translation from Pc1410 was immunoprecipitated with affinity-purified MSG antibodies. The clones were characterized by DNA sequencing of their 3' and 5' ends. Analysis of the untranslated and coding regions demonstrated that the clones contained unique and conserved regions of sequence, but none of the clones were identical. Isolation of seven additional unique clones picked from a single screening of a cDNA library suggests that numerous MSG transcripts exist within a population of P. carinii.
