Introduction of the mouse histone H3.1 gene into tk- mouse L cells by cotransfection with the herpesvirus thymidine kinase gene resulted in the production of two mRNAs from the transfected gene, one with a normal 3' end and the other one with a longer 3'-untranslated region, ending at site X, which was poly(A)+. In contrast, the endogenous histone H3.1 gene only produced a single mRNA. The cryptic poly(A)+ site was only used when the histone H3.1 gene was transfected. To localize possible downstream cryptic processing sites, the hairpin loop at the end of the histone gene was deleted and the resulting deletions were introduced into L cells. Two major mRNAs were produced from this gene, one ending at site X and the major one ending at site Y, which was located 150 nucleotides before site X. Transcription extended downstream of site X efficiently in the endogenous gene, as judged by the extent of transcription of downstream sequences in isolated nuclei. Transcription extended downstream of site X in the transfected gene because the placement of a normal histone 3' end downstream of site X resulted in transcripts that ended at site X and longer transcripts that ended with the new histone 3' end. These results indicate that transcription may normally proceed a substantial distance past the hairpin loop (greater than 500 bases). The formation of the different 3' ends in these transfected genes was due to competition between different processing mechanisms.
